                     NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                     ----------------------------------------------------

1.    General.

      The accompanying condensed consolidated financial statements are
      presented in accordance with the requirements of Form 10-Q and
      generally accepted accounting principles for interim financial
      reporting.  They do not include all disclosures normally made in
      financial statements contained in Form 10-K.  In management's opinion
      all adjustments necessary for a fair presentation of the results of
      operations, financial position and cash flows for the periods shown
      have been made.  All such adjustments are of a normal recurring nature
      except for the provisions for write-down of assets and other matters
      (Note 4) and the cumulative effect of change in accounting principle
      (Note 5).  Results for the three and six months ended June 30, 1996
      are not necessarily indicative of results for the full year 1996.

2.    Discontinued Operations.

      On July 24, 1996, the Company signed an agreement to sell its
      international oil and gas production business to Agip (U.K.) Limited.  
      The sale, which should be completed during the third quarter of 1996,
      is expected to result in an after-tax gain of approximately $115
      million.  The actual gain to be recorded will be determined as of the
      date of sale and will be based on the actual cash proceeds received. 
      Cash proceeds from this divestment should approximate $260 million. 

      The sale of this business represents the completion of the Company's
      withdrawal from oil and gas exploration and production activities. 
      Previously, the Company withdrew from international exploration
      activities in 1992 and divested its remaining 55-percent interest in
      Suncor Inc., its Canadian integrated oil company, in June 1995.  Sun
      received $770 million in pretax cash proceeds from the sale of Suncor,
      after commissions and discounts, of which $635 million was received in
      June 1995 and $135 million was received in June 1996.

      As a result of the decision to sell the international oil and gas
      production business, such business and the previously divested
      Canadian synthetic oil production and conventional oil and gas
      exploration and production operations (collectively, "Canadian
      upstream petroleum operations") have been classified as discontinued
      operations for all periods presented in the condensed consolidated
      financial statements and related footnotes.  The following is a
      summary of results of operations of these businesses for the six
      months ended June 30, 1996 and 1995 (in millions of dollars):

      *Income from discontinued Canadian upstream petroleum operations
       includes a $157 million gain (comprised of a pretax gain of
       $242 million and applicable income taxes of $85 million)
       attributable to the divestment of the Company's remaining 55-percent
       interest in Suncor Inc.

      Revenues from discontinued international production operations
      totalled $131 and $128 million for the six months ended June 30, 1996
      and 1995, respectively.  Revenues from discontinued Canadian upstream
      petroleum operations totalled $271 million during 1995 prior to the

3.    Operations Held for Sale.

        Real Estate Operations

      Sun has been pursuing the disposition of the Company's investment in
      Radnor Corporation, its wholly owned real estate development
      subsidiary, since October 1991.  This business is accounted for as an
      investment held for sale.  As a result, pretax income (loss) from real
      estate operations, which totalled $1 million and $(1) million for the
      six months ended June 30, 1996 and 1995, respectively, has been
      included as a single amount in other income in the condensed
      consolidated statements of operations.  

      The assets and liabilities relating to real estate operations have
      been segregated in the condensed consolidated balance sheets and
      separately reflected as an investment in operations held for sale. 
      Such amounts are detailed as follows:

        Coal and Cokemaking Operations

      In January 1993, Sun decided to sell its coal and cokemaking
      operations.  In connection with this decision, Sun sold its western
      U.S. coal operations during 1993 and certain of its eastern U.S. coal
      operations during 1994.  Prior to June 30, 1995, Sun's coal and
      cokemaking operations had been accounted for as an investment held for
      sale.  However, effective June 30, 1995, the remaining coal and
      cokemaking business became one of the Company's ongoing business units
      and is no longer held for sale.  Accordingly, the accompanying
      condensed consolidated balance sheets of Sun as of June 30, 1996 and
      December 31, 1995 contain the accounts of its coal and cokemaking
      operations on a fully consolidated basis.  The accompanying condensed
      consolidated statements of operations and cash flows reflect coal and
      cokemaking operations on a fully consolidated basis after June 30,
      1995 and as an operation held for sale prior to this date.  The prior
      period condensed consolidated statements of operations and cash flows
      were not restated to give effect to this change in presentation
      because the impact of such a restatement would not have been material.

4.    Write-downs of Assets and Other Matters.

      During the second quarter of 1996, Sun recorded an $85 million ($53
      million after-tax) provision for write-down of assets and other
      matters related to the Company's Philadelphia refinery reconfiguration
      project.  The project is designed to complete the integration of what
      had been two separate facilities (Point Breeze and Girard Point)
      located next to each other in South Philadelphia.  The integration,
      which should be substantially completed by the end of 1996, is
      expected to improve operating efficiencies, lower fixed costs, and
      reduce on-going capital spending and working capital requirements. 
      The provision is comprised principally of the write-off of redundant
      processing units and also includes an accrual for environmental
      remediation activities associated with the reconfiguration.  

      During the second quarter of 1995, Sun recorded a provision to write
      down to net realizable value certain assets in the refining and
      marketing business and to establish accruals for employee terminations
      and related costs.  The following is a summary of the provision for
      write-down of assets and other matters in the condensed consolidated
      statements of operations for the three and six months ended June 30,
      1995 (in millions of dollars):

5.    Change in Accounting Principle.

      Effective January 1, 1995, Sun adopted the provisions of Statement of
      Financial Accounting Standards No. 121, "Accounting for the Impairment
      of Long-Lived Assets and for Long-Lived Assets to be Disposed Of." 
      This statement requires companies to write down long-lived assets that
      are impaired to estimated fair value.  The write-downs recognized in
      the first quarter of 1995 are reflected as a cumulative effect of
      change in accounting principle in the condensed consolidated statement
      of operations and relate to properties to be disposed of in the
      Company's real estate, coal and refining and marketing operations.

      The following table sets forth summary information concerning these
      write-downs (in millions of dollars):

      Other than the cumulative effect, this change did not have a
      significant impact on Sun's results of operations during the first six
      months of 1995.  The results of operations during the first six months
      of 1995 and 1996 for all properties to be disposed of were not
      significant.

6.    Earnings Per Share.

      The primary loss per share for the three and six months ended June 30,
      1996 was computed by dividing losses, after deducting dividends on the
      preference stock issued in August 1995, by the weighted average number
      of common shares outstanding.  Fully diluted earnings per share
      generally are determined by dividing earnings by the weighted average
      number of shares outstanding, assuming redemption of the preference
      shares for common stock.  However, since the assumed redemption of
      preference shares in the three and six months ended June 30, 1996
      would have resulted in a smaller loss per share, fully diluted per
      share amounts are the same as those reported on a primary basis.

7.    Commitments and Contingent Liabilities.

      In 1992, a wholly owned subsidiary of the Company became a one-third
      partner in Belvieu Environmental Fuels ("BEF"), a joint venture formed
      for the purpose of constructing, owning and operating a $225 million
      methyl tertiary butyl ether ("MTBE") production facility in Mont
      Belvieu, Texas.  The construction of the facility, which had an
      initial designed capacity of 12,600 barrels daily of MTBE, was
      completed during 1995.  

      In order to obtain a secure supply of oxygenates for the manufacture
      of reformulated fuels, Sun has entered into a 10-year off-take
      agreement with BEF.  Pursuant to this agreement, Sun will purchase all
      of the MTBE production from the plant.  The minimum price to be paid
      for the first 12,600 barrels daily of MTBE production while a five-
      year nonrecourse term loan financing this project is outstanding is
<PAGE>
<PAGE> 13

      equal to BEF's annual raw material and operating costs associated with
      this production and debt service payments.  Notwithstanding this
      minimum price, Sun has agreed to pay BEF prices through May 2000 which
      approximate those included in existing MTBE long-term sales agreements
      in the marketplace.  These prices have exceeded the minimum price
      required by the loan agreement.  For the last four years the off-take
      agreement is in place, Sun will negotiate a new price with BEF based
      upon the market conditions existing at that time.

      The Company guarantees the outstanding debt of Radnor Corporation, its
      real estate operation held for sale.  Such debt, which is due in
      January 2001, totalled $133 million at June 30, 1996 (Note 3). 

      Sun is subject to numerous federal, state, local and foreign laws
      regulating the discharge of materials into, or otherwise relating to
      the protection of, the environment.  The Comprehensive Environmental
      Response Compensation and Liability Act ("CERCLA") and the Solid Waste
      Disposal Act as amended by the Resource Conservation and Recovery Act
      ("RCRA"), and related state laws subject Sun to the potential
      obligation to remove or mitigate the environmental effects of the
      disposal or release of certain pollutants at Sun's facilities
      including refineries, service stations, terminals, pipelines and truck
      transportation facilities as well as at third-party or formerly-owned
      sites at which contaminants generated by Sun may be located.  Under
      CERCLA, Sun is subject to potential joint and several liability for
      the costs of remediation at sites at which it has been identified as a
      "potentially responsible party" ("PRP").  As of June 30, 1996, Sun had
      been named as a PRP at 49 sites identified or potentially identifiable
      as "Superfund" sites under CERCLA.  Sun has reviewed the nature and
      extent of its involvement at each site and other relevant
      circumstances and, based upon the other parties involved or Sun's
      negligible participation therein, believes that its potential
      liability associated with such sites will not be significant.  Under
      RCRA and related state laws, corrective remedial action has been
      initiated at some of Sun's facilities and will be required to be
      undertaken by Sun at various of its other facilities.  The cost of
      such remedial actions could be significant but is expected to be
      incurred over an extended period of time.  In addition, Sun is
      currently involved in litigation with a private party to determine
      responsibility for remediation at a formerly owned refinery in
      Oklahoma.  Management believes that Sun is fully indemnified for this
      potential liability.

      Sun establishes accruals related to environmental remediation
      activities for work at identified sites where an assessment has
      indicated that cleanup costs are probable and reasonably estimable. 
      The accrued liability for environmental remediation was classified in

</TABLE>

      Pretax charges against income for environmental remediation totalled
      $19 and $6 million for the six months ended June 30, 1996 and 1995,
      respectively.  The $13 million increase was largely attributable to an
      accrual for remediation activities associated with the reconfiguration
      of the Philadelphia refinery (Note 4).  Claims for recovery of
      environmental liabilities that are probable of realization totalled $8
      million at June 30, 1996 and are included in deferred charges and
      other assets in the condensed consolidated balance sheets. 

      Total future costs for environmental remediation activities will
      depend upon, among other things, the identification of additional
      sites, the determination of the extent of contamination of each site,
      the timing and nature of required remedial actions, the technology
      available and needed to meet the various existing legal requirements,
      the nature and extent of future environmental laws, inflation rates
      and the determination of Sun's liability at multi-party sites, if any,
      in light of the number, participation levels and financial viability
      of other parties.  

      Many other legal and administrative proceedings are pending against
      Sun.  The ultimate outcome of these proceedings and the matters
      discussed above cannot be ascertained at this time; however, it is
      reasonably possible that some of them could be resolved unfavorably to
      Sun.  Management believes that any expenditures attributable to these
      matters will be incurred over an extended period of time and will be
      funded from Sun's net cash flow from operating activities.  Although
      the ultimate impact of these matters could have a significant impact
      on results of operations or cash flow for any future quarter or year,
      management believes that any liabilities which may arise pertaining to
      such matters would not be material in relation to the consolidated
      financial position of Sun at June 30, 1996.  Furthermore, management
      believes that the overall costs for environmental activities will not
      have a material impact, over an extended period of time, on Sun's cash
      flow or liquidity.

Analysis of Earnings Profile of Sun Businesses
- ----------------------------------------------

In the six-month period ended June 30, 1996, Sun had a net loss of $8
million, or $.41 loss per share of common stock, compared with net income
of $44 million, or $.41 per share of common stock, for the first half of
1995.  Excluding the special items shown separately in the Earnings Profile
of Sun Businesses, Sun earned $45 million in the first six months of 1996
compared to $35 million in the first six months of 1995.  

Sun Northeast Refining -- The Sun Northeast Refining business, which
consists of the manufacturing and wholesale marketing of fuels produced at
Sun's Marcus Hook, PA and Philadelphia, PA refineries, had a loss of $24
million in the first six months of 1996 compared to a loss of $37 million
in the first half of 1995.  The decline in the operating loss was due
primarily to higher average wholesale fuels product margins ($29 million),
partially offset by higher refinery operating expenses ($15 million) caused
largely by an increase in refinery fuel costs.  The improvement in
wholesale fuels margins reflects the favorable impact of stronger market
conditions for distillate products, partially offset by lower wholesale
gasoline and asphalt margins.  Increased planned refinery maintenance
activity also adversely impacted operating results during the first half of
1996.  

Sunoco Northeast Marketing -- The Sunoco Northeast Marketing business,
which consists of the retail sale of gasoline and middle distillates in New
England and the Mid-Atlantic states and convenience-store operations in
these regions, earned $6 million in the current six-month period versus $5
million in the first half of 1995.  The increase in operating results was
due to higher retail gasoline margins ($8 million), essentially offset by
an increase in marketing expenses.  

Sunoco Chemicals -- The Sunoco Chemicals business consists of the
manufacturing and marketing of commodity and intermediate petrochemicals
produced at the Marcus Hook and Philadelphia refineries, at an ethylene
oxide plant in Brandenburg, KY and at a joint venture MTBE facility in Mont
Belvieu, TX.  Sunoco Chemicals earned $18 million in the first half of 1996
versus $42 million in the first six months of 1995.  The decline in
earnings was primarily due to significantly lower margins for most
petrochemicals products compared to the strong margins experienced in the
first half of 1995.  Production shortfalls due to maintenance activities at
Sun's Northeast refineries also negatively impacted Sunoco Chemicals during
the first half of 1996.

Sunoco Lubricants -- The Sunoco Lubricants business, which is comprised of
the manufacturing, packaging and marketing of lubricating and specialty
oils produced at Sun's Tulsa, OK and Puerto Rico refineries as well as the
related manufacturing and wholesale marketing of fuels produced at these
facilities, lost $1 million in the 1996 first half, compared to a loss of
$11 million in the first six months of 1995.  The improvement in operating
results was primarily due to higher sales volumes of both lubricants ($9
million) and related fuels ($6 million) reflecting an increase in refinery
production levels and to higher margins on wholesale fuels products ($11
million) primarily resulting from a stronger market for distillate
products.  These positive factors were partially offset by the impact of
<PAGE>
<PAGE> 18

lower margins on lubricant products ($5 million) and higher operating
expenses ($10 million) largely attributable to an increase in refinery fuel
costs.  

Sunoco MidAmerica Marketing & Refining -- The Sunoco MidAmerica Marketing &
Refining business consists of the retail sale of gasoline and middle
distillates and convenience-store operations in the midwestern U.S.
(primarily Ohio and Michigan) as well as the manufacturing and wholesale
marketing of fuels and petrochemicals produced at Sun's Toledo, OH
refinery.  Sunoco MidAmerica Marketing & Refining earned $1 million during
the first half of 1996, compared to a loss of $12 million in the 1995 first
half.  Improved fuels margins ($20 million), particularly in the wholesale
market, more than offset the decline in margins on petrochemicals (largely
xylene) produced at the Toledo refinery ($9 million).  Higher refinery
production levels and lower expenses in the retail side of the business
were offset by higher refinery fuel costs.  

Sunoco Logistics -- The Sunoco Logistics business, which consists of
pipeline transportation of crude oil and refined petroleum products,
domestic crude oil acquisition from third-party leases, crude oil trucking
and the Nederland, TX crude oil terminalling operation, earned $26 million
in the first six months of 1996 versus $25 million in the year-ago period. 
The increase was due largely to higher earnings from Sun's joint venture
pipeline systems.  

Sun Coal and Coke -- The Sun Coal and Coke business consists of coal
production from mines in Virginia and Kentucky and coke manufacturing at
the Company's facility in Vansant, VA.  Sun Coal and Coke earned $15
million in the first half of 1996 versus $12 million in the first half of
1995.  The increase in earnings was due to improved operations ($2 million)
and higher coke margins ($1 million).

Net Financing Expenses -- Net financing expenses were down $8 million
versus the year-ago period due to lower average total borrowings as the
Company substantially reduced its debt level in the second half of 1995.   

Real Estate Operations Held for Sale -- Real estate operations held for
sale earned $1 million in the current half versus break-even results during
the first half of 1995.  For a further discussion of Sun's real estate
operations held for sale, see Note 3 to the condensed consolidated
financial statements.

Sun International Production -- Sun International Production earnings were
$38 million in the 1996 first half, compared with $32 million in the first
six months of 1995.  The increase in earnings was attributable to higher
crude oil prices.  

On July 24, 1996, the Company signed an agreement to sell its international
oil and gas production business to Agip (U.K.) Limited.   The sale, which
should be completed during the third quarter of 1996, is expected to result
in an after-tax gain of approximately $115 million.  The actual gain to be
recorded will be determined as of the date of sale and will be based on the
actual cash proceeds received.  Cash proceeds from this divestment should
approximate $260 million.  Sun is considering several options for the use
of these proceeds including investment in its ongoing operations and the
repurchase of Sun stock.  For additional information, see Note 2 to the
condensed consolidated financial statements.

Analysis of Consolidated Statements of Operations 
- -------------------------------------------------

Sales and other operating revenue increased $289 million, or 6 percent,
principally due to higher domestic refined product sales volumes ($251
million) and prices ($199 million), higher revenues from resales of
purchased crude oil and refined products ($250 million) and the inclusion
in the first half of 1996 of sales and other operating revenue attributable
to Sun's coal and cokemaking business ($83 million) (see Note 3 to the
condensed consolidated financial statements).  Partially offsetting these
positive factors were lower sales and other operating revenue attributable
to Canadian refining and marketing operations ($525 million, including
Canadian consumer excise taxes of $207 million) as a result of the
divestment of Suncor on June 8, 1995.  Interest income increased $4 million
principally due to interest earned on the installment note receivable from
the divestment of Suncor, which was collected in June 1996.  Other income
increased $6 million due to higher equity in earnings of affiliated
companies ($4 million).  

Cost of products sold and operating expenses increased $497 million, or 14  
percent, primarily due to higher domestic crude oil and refined product
acquisition costs ($361 million), higher resales of purchased crude oil and
refined products ($252 million), higher domestic refinery operating
expenses ($54 million) and the inclusion in the first half of 1996 of costs
attributable to Sun's coal and cokemaking business ($57 million).  The
increase in cost of products sold and operating expenses was partially
offset by lower costs and operating expenses attributable to the divestment
of Canadian refining and marketing operations ($281 million).  Selling,
general and administrative expenses decreased $50 million, or 15 percent,
due to lower Canadian refining and marketing expenses as a result of the
Suncor divestment.  Taxes, other than income taxes decreased $179 million,
or 18 percent, principally due to lower consumer excise taxes ($174
million) attributable to the Suncor divestment.  Depreciation, depletion
and amortization increased $1 million, or 1 percent, primarily as a result
of higher depreciation at Sun's domestic refining and marketing operations
and the inclusion in the first half of 1996 of amounts attributable to
Sun's coal and cokemaking business, partially offset by the decline
resulting from the Suncor divestment.  For a discussion of the provisions
for write-down of assets and other matters recorded in the second quarters
of 1996 and 1995, see Note 4 to the condensed consolidated financial
statements.  Interest cost and debt expense decreased $15 million, or 27
percent, due to lower average borrowings.  For a discussion of the
cumulative effect of change in accounting principle, see Note 5 to the
condensed consolidated financial statements.

Analysis of Earnings Profile of Sun Businesses
- ----------------------------------------------

In the three-month period ended June 30, 1996, Sun had a net loss of $3
million, or $.19 per share of common stock, compared with net income of
$138 million, or $1.29 per share of common stock, for the second quarter of
1995.  Excluding the special items shown separately in the Earnings Profile
of Sun Businesses, Sun earned $50 million in the second quarter of 1996
compared to $42 million in the second quarter of 1995.  

Sun Northeast Refining -- The Sun Northeast Refining business earned $4
million in the second quarter of 1996 versus break-even in the second
quarter of 1995.  The improvement was due primarily to higher average
wholesale fuels product margins ($10 million), partially offset by higher
refinery operating expenses ($8 million).  The improvement in wholesale
fuels margins reflects the favorable impact of stronger market conditions
for distillate products, partially offset by lower margins for wholesale
gasoline (particularly premium) and asphalt.  The higher refinery operating
expenses were due largely to higher refinery fuel costs (both produced and
purchased) resulting from higher crude oil and natural gas prices.

Sunoco Northeast Marketing -- The Sunoco Northeast Marketing business
earned $7 million in the current quarter versus a loss of $2 million in the
second quarter of 1995.  The increase in operating results was due to
improved retail gasoline margins, as Sunoco Northeast Marketing began to
recover the rapid run-up in crude oil prices that occurred in the first
quarter of 1996.  Partially offsetting this positive factor was an increase
in marketing expenses.  

Sunoco Chemicals -- Sunoco Chemicals earned $11 million in the second
quarter of 1996 versus $22 million in the second quarter of 1995.  The
decline in earnings was primarily due to significantly lower margins ($9
million) for most petrochemicals products compared to the strong margins
experienced in the second quarter of 1995.  

Sunoco Lubricants -- The Sunoco Lubricants business lost $3 million in the
1996 second quarter, compared to a loss of $2 million in the 1995 second
quarter.  The adverse impacts of significantly higher average crude oil
costs on lubricants and residual fuel margins and increased refinery
natural gas costs were largely offset by a 17 percent increase in
lubricants sales volumes, higher refinery production volumes and stronger
distillate margins.  

Sunoco MidAmerica Marketing & Refining -- Sunoco MidAmerica Marketing &
Refining earned $5 million during the 1996 second quarter, compared to
earnings of $1 million in the 1995 second quarter.  Improved fuels margins
in the wholesale market ($6 million), higher refinery production levels ($3
million) and lower expenses in the retail side of the business ($3 million)
more than offset the impact of lower chemicals margins ($3 million) and
higher refinery expenses ($6 million) which resulted from an increase in
refinery fuel costs.  

Sunoco Logistics -- The Sunoco Logistics business earned $15 million in the
second quarter of 1996 versus $13 million in the year-ago period.  The
increase was largely due to higher earnings from Sun's joint venture
pipeline systems and from its Nederland terminal operations.  
<PAGE>
<PAGE> 22

Net Financing Expenses -- Net financing expenses totalled $11 million for
the second quarter of 1996 compared to $17 million for the second quarter
of 1995.  The decrease was primarily due to lower average total borrowings
as the Company substantially reduced its debt level in the second half of
1995.

Real Estate Operations Held for Sale -- Real estate operations held for
sale earned $1 million in the current quarter versus break-even results for
the year-ago period.  For a further discussion of Sun's real estate
operations held for sale, see Note 3 to the condensed consolidated
financial statements.

Sun International Production -- Sun International Production earnings were
$19 million in the 1996 second quarter versus earnings of $13 million in
the 1995 second quarter.  The increase in earnings was attributable to
higher crude oil prices ($3 million) and higher natural gas volumes ($3
million).

Special Items -- For a discussion of the special items shown separately in
the Earnings Profile of Sun Businesses, see Notes 2 and 4 to the condensed
consolidated financial statements.

Analysis of Consolidated Statements of Operations 
- -------------------------------------------------

Sales and other operating revenue increased $306 million, or 12 percent,
principally due to higher domestic refined product sales volumes ($192
million) and prices ($95 million), higher revenues from resales of
purchased crude oil and refined products ($163 million) and the inclusion
in the second quarter of 1996 of sales and other operating revenue
attributable to Sun's coal and cokemaking business ($42 million).  
Partially offsetting these positive factors were lower sales and other
operating revenue attributable to the divested Canadian refining and
marketing operations ($219 million, including Canadian consumer excise
taxes of $86 million).  Other income increased $2 million primarily due to
higher equity in earnings of affiliated companies ($1 million).  

Cost of products sold and operating expenses increased $363 million, or 20
percent, primarily due to higher domestic crude oil and refined product
acquisition costs ($235 million), higher resales of purchased crude oil and
refined products ($163 million), higher domestic refinery operating
expenses ($32 million) and the inclusion in the second quarter of 1996 of
costs attributable to Sun's coal and cokemaking business ($30 million). 
The increase in cost of products sold and operating expenses was partially
offset by lower costs and operating expenses attributable to the divested
Canadian refining and marketing operations ($114 million).  Selling,
general and administrative expenses decreased $14 million, or 8 percent,
primarily due to lower Canadian refining and marketing expenses as a result
of the Suncor divestment, partially offset by higher domestic marketing
expenses.  Taxes, other than income taxes decreased $58 million, or 12
percent, principally due to lower consumer excise taxes ($57 million)
resulting from the Suncor divestment.  Depreciation, depletion and
amortization increased $2 million, or 3 percent, primarily as a result of
higher depreciation at Sun's domestic refining and marketing operations and
the inclusion in the second quarter of 1996 of amounts attributable to
Sun's coal and cokemaking business, partially offset by the decline

resulting from the Suncor divestment.  For a discussion of the provisions
for write-down of assets and other matters recorded in the second quarters
of 1996 and 1995, see Note 4 to the condensed consolidated financial
statements.  Interest cost and debt expense decreased $8 million, or 29
percent, due to lower average borrowings.  


                                      FINANCIAL CONDITION

Cash and Working Capital 
- ------------------------

At June 30, 1996, Sun had cash and cash equivalents of $64 million compared
to $11 million at December 31, 1995, and had working capital of $121
million compared to working capital of $109 million at December 31, 1995. 
Sun's working capital position is considerably stronger than indicated
because of the relatively low historical costs assigned under the LIFO
method of accounting for most of the inventories reflected in the condensed
consolidated balance sheet.  The current replacement cost of all such
inventories exceeds the carrying value at June 30, 1996 and December 31,
1995 by $563 million and $528 million, respectively.  Inventories valued at
LIFO, which consist of crude oil and refined products, are readily
marketable at their current replacement values.  Management believes that
the current levels of Sun's cash and working capital provide adequate
support for ongoing operations.

Cash Flows and Financial Capacity 
- ---------------------------------

In the first six months of 1996, Sun's net cash provided by operating
activities was $146 million compared to $5 million in the first six months
of 1995.  This $141 million improvement was largely due to a decrease in
working capital uses pertaining to operating activities, partially offset
by a decline in net cash provided by discontinued operations.  

Divestment activities have also been a source of cash and have enhanced
liquidity.  In June 1996, Sun received the final cash proceeds from the
sale of Suncor.  As a result of the sale, Sun has received total pretax
cash proceeds of $770 million, of which $635 million was received in June
1995 and $135 million was received in June 1996.

Management believes that future cash provided by continuing operations
("cash generation") will be sufficient to satisfy Sun's capital
requirements and to pay the current cash dividends on common and preference
stock.  However, from time to time, the Company's short-term cash
requirements may exceed its cash generation due to various factors
including volatility in crude oil and refined product markets and increases
in capital spending and working capital levels.  During those periods, the
Company may supplement its cash generation with proceeds from divestment
and financing activities.  In the event that cash generation and divestment
proceeds are insufficient to satisfy near-term cash requirements, the
Company has access to $600 million of short-term financing in the form of
commercial paper and revolving credit agreements from commercial banks. 
The Company also has access to short-term financing under non-committed
money market facilities.

</TABLE>

As of June 30, 1996, Sun's debt-to-capital ratio was 35.3 percent. 
Management believes there is sufficient borrowing capacity available to
provide for Sun's future cash requirements.

                                       OTHER INFORMATION

Item 1.     Legal Proceedings

      Many legal and administrative proceedings are pending against Sun. 
      Although the ultimate outcome of these proceedings cannot be
      ascertained at this time, it is reasonably possible that some of them
      could be resolved unfavorably to Sun.  Management of Sun believes that
      any liabilities which may arise from such proceedings, including those
      discussed above, would not be material in relation to the consolidated
      financial position of Sun at June 30, 1996.

Item 4.     Submission of Matters to a Vote of Security Holders

      The Annual Meeting of the Company's shareholders was held on May 2,
      1996. Proxies for the meeting were solicited pursuant to Section 14(a)
      of the Securities Exchange Act of 1934 and there was no solicitation
      in opposition to the Company's solicitations. At this meeting, the
      shareholders were requested (1) to act upon the appointment of
      independent accountants and (2) to elect a Board of Directors. The
      following action was taken by the Company's shareholders with respect

             chargeable gains, only in relation to disposals, the
             subject of paragraph (a) and only to the extent that
             the computation produces a chargeable gain or allowable
             loss), the same shall be reduced by the percentage
             equal to the applicable percentage rate of the
             appropriate tax (not being, in the case of corporation
             tax, the small companies' rate) for the relevant
             accounting period in which the amount in question
             becomes payable or receivable (irrespective of whether
             that is a period for which tax payable by the Company
             or either of the Subsidiaries is in fact reduced or
             increased by reference to the item or the amount
             payable or receivable, and irrespective of the
             availability of any other reliefs or allowances).  In
             relation to whether the provisions of this clause
             3.3(b) apply:

             (i)   the Purchaser agrees to procure that, unless
                   Seller otherwise agrees in writing, the Group
                   shall prepare and submit any computations and
                   returns required for the purposes of the Group's
                   Taxation affairs as if they do so apply;  and

             (ii)  in the event that any Taxation Authority queries
                   whether they do so apply, the provisions of clause
                   5 of the Deed of Tax Indemnity shall apply as if
                   such query were a Claim (as defined in the Deed of
                   Tax Indemnity).

      (c)    If pursuant to clause 3.3(b) it has initially been
             assumed that an amount can or should so be taken into
             account as a deduction or receipt and subsequently it
<PAGE>
<PAGE> 20

             is finally determined not to be a deduction or receipt
             in computing any liability to Taxation of the Company
             or any one of the Subsidiaries, Seller shall promptly
             pay to Purchaser an amount equal to the amount by which
             the relevant item had been previously reduced.

             If pursuant to clause 3.3(b), it has initially been
             assumed that an amount cannot or should not be taken
             into account as a deduction or receipt and subsequently
             it is finally determined to be a deduction or receipt
             in computing any liability to Taxation of the Company
             or either of the Subsidiaries, Purchaser shall promptly
             pay to Seller an amount equal to the amount by which
             the relevant item would have been so reduced, if it had
             been initially assumed to be a deduction or receipt. 
             Any payments pursuant to this clause 3.3(c) shall not
             be regarded as Adjustments.

      (d)    Any adjustment to the amount specified in clause 3.1
             required pursuant to the provisions of this clause will
             be effected (and any payment made) in the manner
             provided in the following sub-clauses.

      Estimate of Adjustments
      -----------------------

3.4   Seller shall provide Purchaser with a written statement
      setting out the sum of the Preliminary Net Working Capital
      and an estimate of all Adjustments which are expected to be
      required by clause 3.3 together with an estimate of the
      amount payable equivalent to interest in accordance with
      clause 3.9.  Such statement shall be provided as soon as
      practicable, but in any event no less than three Business
      Days, prior to Completion.  Prior to Completion, Seller may
      update the same and the Parties shall, without prejudice to
      clause 3.7, endeavour to agree such estimates before
      Completion, failing which the matter shall be dealt with in
      accordance with clauses 3.5 and 3.7.  Seller shall provide
      Purchaser (and its advisers) with such evidence in respect
      of such estimates as Purchaser may reasonably require,
      including access to relevant employees of the Company in
      order to obtain further information in respect of such
      estimates.

3.5   If any of the amounts or portions of such estimates to be
      delivered pursuant to clause 3.4 have not been agreed prior
      to Completion, the disputed amounts or portions of the
      Adjustments shall be left out of account, and the undisputed
<PAGE>
<PAGE> 21

      Dollar balances of the Adjustments shall be set off against
      each other.

      The resultant balance shall be added to, or subtracted from
      (as the case may be), the amount stated in clause 3.1, and
      such amount so adjusted shall be payable at Completion. 
      Payment of disputed amounts or portions thereof shall be
      made within five Business Days following agreement of the
      Parties or determination under clause 3.7.

3.6   The Accounts and Final Adjustments
      ----------------------------------

      (a)    (i)    As soon as practicable after the date hereof but,
                    in any event, within 60 days after the Economic
                    Date Seller shall procure that the Accounts are
                    prepared by the Company and audited by the
                    Auditors in accordance with this clause 3.6 and
                    submitted to Purchaser together with a statement
                    prepared by Seller in the form set out in
                    Schedule 9, showing the Net Working Capital in
                    both Sterling and Dollars (such statement being
                    extracted from the Accounts save as otherwise
                    provided in this Agreement).

             (ii)   Within 15 days after Completion Seller shall
                    submit to Purchaser a revised statement of the
                    Adjustments (if any) required to be made pursuant
                    to clause 3.3.

             (iii)  Any amounts required to be included in the
                    statements referred to in paragraphs (i) and (ii)
                    which are denominated in Pounds shall be
                    translated into Dollars at the Translation Rate.

      (b)    The Accounts shall consist of a balance sheet, profit
             and loss account and notes for the Company and each of
             the Subsidiaries together with a consolidated balance
             sheet of the Group as at close of business on the
             Economic Date and a consolidated profit and loss
             account of the Group in respect of the period from 1st
             January 1996 to the Economic Date (both dates
             inclusive).

      (c)    The Accounts shall:

             (i)    be prepared under the historical cost convention
                    and in accordance with the requirements of
                    generally accepted accounting practices and
<PAGE>

                    principles, Statements of Standard Accounting
                    Practice and Financial Reporting Standards in the
                    United Kingdom as of the Economic Date
                    consistently applied and, subject to the
                    foregoing

             (ii)   show a true and fair view of the state of affairs
                    of the Company and the Subsidiaries at the
                    Economic Date and the profit (or loss) of the
                    Company and the Subsidiaries for the period from
                    1st January 1996 to the Economic Date and in the
                    case of the consolidated financial statements
                    show a true and fair view of the state of affairs
                    of the Group as a whole at the Economic Date
                    (and, for the avoidance of doubt, inventories
                    shall be classified as fixed assets for the
                    purposes of the Accounts) and, subject to the
                    foregoing

             (iii)  apply and adopt the same bases and policies of
                    accounting as applied or adopted for the audited
                    consolidated accounts of the Company and SONSL as
                    at 31st December, 1995 PROVIDED THAT where those
                    bases and policies are inconsistent with those
                    referred to in paragraph (i), the bases and
                    policies referred to in paragraph (i) shall
                    prevail, PROVIDED FURTHER THAT notwithstanding
                    any of the foregoing an amount of $13,286,500
                    attributable to monies received by the Company
                    under contracts for the sale of gas where the
                    corresponding quantity of gas has not been
                    delivered thereunder shall be treated as
                    "deferred income" and not as a "current
                    liability" notwithstanding that it was treated as
                    such in the audited consolidated accounts of the
                    Company and SONSL for the year ended 31st
                    December 1995 PROVIDED FURTHER THAT in relation
                    to any current (and not deferred) liability of
                    the Company or the Subsidiaries to PRT or
                    corporation tax, the Accounts will only take
                    account of such liabilities to the extent that
                    such liabilities are expected to be payable;

             (iv)   treat any amount of advance corporation tax not
                    estimated as being capable of set off against any
                    liability to corporation tax of the Group for
                    accounting periods up to and including the
                    Economic Date as an offset against deferred taxes
                    for the purposes of the Accounts.

             (v)    shall translate all sums denominated in Pounds
                    into Dollars at the Translation Rate.

      (d)    (i)    Unless Purchaser shall notify Seller in writing
                    within 30 days after Completion that it does not
                    accept that the Accounts and the Statements
                    delivered under sub-clause 3.6(a)(i) and (ii)
                    (together "the Adjustment Documents") are
                    correct, Purchaser shall be deemed to have
                    accepted the correctness of all such documents
                    for the purpose of determining the Consideration.

             (ii)   If, within the period of 30 days after Completion
                    Purchaser shall notify Seller in writing that it
                    does not accept the correctness of any of the
                    Adjustment Documents in any respect the Parties
                    shall use their best endeavours to reach
                    agreement upon any adjustments required to the
                    Accounts and/or either of the statements to meet
                    the objections of the Purchaser.

             (iii)  If the Parties are unable to reach agreement as
                    aforesaid within 15 days of the notification
                    referred to in paragraph (ii) the provisions of
                    clause 3.7 shall apply.

             (iv)   If Purchaser accepts or is deemed to accept that
                    the Adjustment Documents are correct the
                    Adjustment Documents as so accepted or, as
                    determined pursuant to clause 3.7 shall be final
                    and binding on the Parties for the purpose of
                    determining the Consideration.

      (e)    Within 7 days following agreement, deemed agreement or
             determination of the Adjustment Documents:

             (i)    Seller shall pay to Purchaser (if the Net Working
                    Capital is a greater negative amount than the
                    Preliminary Net Working Capital) or Purchaser
                    shall pay to Seller (if the Net Working Capital
                    is a smaller negative amount than the Preliminary
                    Net Working Capital) by way of adjustment to the
                    amount specified in clause 3 the Net Working
                    Capital Adjustment; and

             (ii)   Seller shall pay to Purchaser or, as the case may
                    be, Purchaser shall pay to Seller, any amount
                    payable under clause 3.3 (as shown in the
<PAGE>
<PAGE> 24

                    statement delivered under sub-clause 3.6(a)(ii)
                    as so agreed or determined) to the extent not
                    already paid or taken into account on Completion.

             Any amount not so paid shall carry interest at the
             Agreed Rate plus 3% from the due date until the date of
             actual payment (as well after judgment as before).

      Independent determination
      -------------------------

3.7   If the Parties cannot reach agreement on the contents of all
      or part of the Adjustment Documents within the time limit
      provided in clause 3.6(d)(iii), the disputed items may be
      referred by either Party for determination by an independent
      chartered accountant nominated by the Parties or, in the
      absence of agreement between the Parties within five
      Business Days of a Party notifying the other that it
      proposes to refer the dispute to an expert, by the President
      of the Institute of Chartered Accountants in England and
      Wales.  Subject to clause 4.3, the nominated chartered
      accountant shall be afforded such access to books, records,
      accounts and documents in the possession of each of the
      Parties as he may reasonably request, and he shall act as
      expert not as arbitrator.  The said accountant's
      determination shall, in the absence of fraud or manifest
      error or bias, be final and binding on the Parties, his fees
      and disbursements shall be borne by the Parties in equal
      shares and the Parties shall bear their own costs in respect
      of such reference.

3.8   Seller shall provide Purchaser with copies of all relevant
      documentation in support of the Adjustment Documents and
      shall liaise with Purchaser on the compilation and agreement
      of the Adjustment Documents.  Purchaser shall, and shall
      procure that the Company shall, render Seller all assistance
      reasonably required for the preparation, compilation and
      agreement of the Adjustment Documents.

      Time-Value Adjustments
      ----------------------

3.9   (a)    There shall be payable by Purchaser to Seller, 

             (i)    an amount equivalent to interest calculated at
                    the Agreed Rate  from the Economic Date up to and
                    including the Completion Date on the amount
                    specified in clause 3.1 less the amount of the
<PAGE>
<PAGE> 25

                    Preliminary Net Working Capital and any amount
                    deducted at Completion from the amount specified
                    in clause 3.1 in respect of the Adjustments
                    specified in clause 3.3,

                    less

             (ii)   if and to the extent that the Inter-Company
                    Receivable exceeds the Inter-Company Debt an
                    amount equivalent to interest calculated at the
                    Agreed Rate on the amount which is one half of
                    the sum of the amount of such excess on the first
                    day of a Calculation Period and the amount of
                    such excess on the last day of that Calculation
                    Period, for each Calculation Period commencing on
                    the date hereof.

      (b)    In respect of the Adjustments Seller or Purchaser (as
             the case may be) shall pay:

             (i)    an amount equivalent to interest at the Agreed
                    Rate on the Net Working Capital Adjustment from
                    the Economic Date up to and including Completion,
                    and, in the case of disputed items, up to and
                    including the date of settlement thereof; and

             (ii)   an amount equivalent to interest at the Agreed
                    Rate on each amount payable or receivable under
                    clause 3.3(a) (adjusted in accordance with clause
                    3.3(b)) from the date of the payment or receipt
                    thereof by any member of the Group up to and
                    including the Completion Date or, in the case of
                    disputed items, up to and including the date of
                    settlement thereof.

      (c)    If and to the extent that any amount equivalent to
             interest (whether paid in respect of amounts taken into
             account at Completion or in respect of amounts settled
             thereafter, as provided in this clause 3.9) is or is
             treated as interest for the purposes of Taxation, such
             amounts shall be treated as short interest and no
             deduction shall be made therefrom.

      (d)    Notwithstanding any of the foregoing, the maximum
             aggregate amount payable by Purchaser to Seller
             pursuant to this clause 3.9 shall be $2,000,000.

3.10  If at the time when the Parties shall seek to determine the
      Adjustments pursuant to clause 3.4, either Party notifies
<PAGE>
<PAGE> 26

      the other that an item not referred to in the definition of
      "Net Working Capital" should be so included ("a Relevant
      Item"), the Parties shall seek to agree the treatment of
      such item provided that if the Parties shall fail so to
      agree within 14 Business Days of such notice, clause 3.7
      shall apply, mutatis mutandis save that the words "on the
      content of all or part of the Adjustment Documents within
      the time limit provided in clause 3.6(d)(iii)" in clause 3.7
      shall be replaced by the words "on the treatment of a
      Relevant Item within the time limit provided in clause
      3.10".

3.11  The provisions of clause 3.3(b) and 3.3(c) shall apply
      mutatis mutandis to the retention bonuses referred to in
      paragraph (e) of the definition of "Net Working Capital"
      assumed to be deductible or otherwise capable of being
      claimed as a relief in computing the Company's liability to
      Taxation.

4     Interim Period
      --------------

4.1   During so much of the Interim Period as falls after the date
      hereof, Seller shall

      (a)    (i)    ensure that subject to any limitations imposed by
                    the terms of any of the Licensed Interest
                    Documents, as to which Seller shall request the
                    relevant parties thereto to release or waive such
                    limitation if requested by Purchaser, Purchaser
                    and any person authorised by it shall be given
                    full access at reasonable times to the Premises
                    and all Data (whether in the possession or
                    control of the Company and the Subsidiaries at
                    the date hereof or as such Data comes into the
                    possession or control of the Company and the
                    Subsidiaries during the Interim Period), title
                    deeds, books and records, directors, employees
                    and assets of the Company and the Subsidiaries,
                    and the directors and employees of the Company
                    and the Subsidiaries shall give promptly all such

                      practicable in the circumstances);

             PROVIDED THAT Seller shall not be in breach of its
             obligations under this paragraph (d) if any such
             expenditure is approved pursuant to the terms of any
             relevant Licensed Interest Document if the Company or

                      agreements specified in clause 6.5(a)(vii));

      (f)    the Company and the Subsidiaries will conduct their
             business in the ordinary course and in a proper and
             prudent manner and in accordance with good oil field

             meet all expenditure (including insurance costs) and
             receive all income in respect of the Licensed

      (g)    in respect of such policies of insurance as are
             maintained by the Company and/or the Subsidiaries and
             are in force at the date hereof, the Company and the
             Subsidiaries or, where applicable, a member of the
             Seller Group shall maintain in full force and effect
             such policies of insurance, shall pay all premiums
             falling due for payment by the Company or the
             Subsidiaries or, where applicable, a member of the

             deductible arising under any such policy in respect of
             any claim occurring or arising during the Interim
             Period shall be for the account of the Company and/or
             the Subsidiaries and none of the Purchaser, the Company
             or the Subsidiaries shall have any claim or other right
             against Seller in respect of such deductible under this
             Agreement.  Seller shall procure that, following
             termination of such insurance on the Completion Date,
             there shall be rebated to the Company and/or the
             Subsidiaries so much of the premiums paid or borne by
             them as it receives by way of reimbursement as a result
             of early termination; and

      (h)    no new employee will be engaged by the Company or any
             of the Subsidiaries except in the ordinary and proper
             course of business and on terms which, when considered
             overall, as far as practicable would be similar to
             those applicable to existing employees carrying out the
             same functions or of the same seniority and no Employee
             will be dismissed except in the ordinary course of
             business.

4.2   (a)    Without prejudice to clause 4.1, Seller shall (subject
             to any confidentiality obligations by which it is
             bound) ensure that, pending Completion, Purchaser is
             kept fully informed in a timely manner, and is fully
             consulted in relation to, all material matters in
             relation to the Licence Interests, including, but not
             limited to:

             (i)      the making of any cash call;

             (ii)     the approval of any AFE;

             (iii)    the adoption or proposal of, or amendment to,
                      any work programme and budgets; 

             (iv)     the receipt of any Operators' billing statements
                      and invoices;

             (v)      the receipt of any Data.

      (b)    To the extent that Seller is restricted, as a result of
             confidentiality obligations binding on it or on the
             Company or the Subsidiaries from procuring that
             Purchaser is kept fully informed as aforesaid, or from
             giving it access to information or documentation as
             referred to in clause 4.1 above, Seller shall use all
             reasonable endeavours to remove such restriction,
             whether by seeking from the party or parties to whom
             such obligations of confidentiality are owed a waiver
             of its or their rights, or otherwise.  If any costs or
             charges would be payable to any third party in respect
             of the lifting of any confidentiality restriction in
             its favour, Seller shall so notify Purchaser and
             Purchaser shall, if it wishes Seller to proceed, hold
             Seller harmless against such costs or charges.
<PAGE>
<PAGE> 33

4.3   Prior to Completion, Purchaser shall hold in confidence all
      information furnished or disclosed to Purchaser by Seller in
      connection with the transactions contemplated by this
      Agreement as well as all information concerning the Group
      and the Licence Interests contained in any analyses,
      compilations, studies or other documents and any business
      and/or commercial information in respect of Seller and any
      information acquired by the financial controller of
      Purchaser referred to in clause 4.5 (collectively, the
      "Information").  However, the undertaking of confidentiality
      above shall not extend to any Information which is:

      (a)    generally available to the public other than as a
             result of a wrongful disclosure by Purchaser; or

      (b)    available to Purchaser as owner of or otherwise
             entitled to such information without any restriction on
             disclosure; or

      (c)    available to Purchaser on a non-confidential basis from
             a source other than Seller if such source is entitled
             to disclose such information; or

      (d)    lawfully requested by a Government agency or any court
             of competent jurisdiction, or is required to be
             disclosed by regulation of any recognised stock
             exchange or the Securities and Exchange Commission or
             other similar body; or

      (e)    already in the possession of Purchaser otherwise than
             as a result of a breach of an obligation of
             confidentiality by a third party of which Purchaser is,
             or ought reasonably to have been, aware.

      Purchaser shall not, without the prior written consent of
      Seller (which shall not be unreasonably withheld or
      delayed), release or disclose any Information to any other
      person, except to Purchaser's or its Affiliates' officers,
      directors, employees, accountants, lawyers, representatives,
      agents, consultants and financial advisers who need to know
      the Information in connection with the implementation or
      financing of the transactions contemplated by this Agreement
      and the Proposed Reorganisation, who are informed by
      Purchaser of the confidential nature of the Information and
      who Purchaser will ensure will observe the terms and
      conditions of this clause 4.3 without the benefit of this
      exception.

4.4   (a)    If Completion does not take place for any reason
             provided for in this Agreement Purchaser shall remain
             bound by clause 4.3, notwithstanding any termination of
             this Agreement, until the earlier of the tenth
             anniversary of such termination or such time as it has
             entered into a separate undertaking of confidentiality
             on the same or similar terms in respect of the
             Information (and this clause 4.4 shall also survive
             until such time).

      (b)    If this Agreement is terminated as aforesaid, Purchaser
             shall, at the request of Seller and at Seller's cost,
             promptly return to Seller (and delete from Purchaser's
             systems, where electronically stored) all the
             Information save where any of the exceptions set out in
             paragraphs (a) to (e) in clause 4.3 applies.

4.5   Following the date hereof and until Completion:

      (a)    Purchaser shall be entitled to place a financial
             controller employed by Purchaser with the Company for
             the purpose of familiarising himself with the financial
             systems and operations of the Company and of monitoring
             the financial transactions of the Company (but so that
             such financial controller shall have no right or
             ability to transact business on behalf of the Company
             or to prevent any such transactions from being carried
             out); and

      (b)    Seller shall procure that the Auditors shall, so far as
             practicable, liaise with the Purchaser's Accountants
             and provide them with access to all working papers used
             in auditing the Accounts.

4.6   If, during the Interim Period, Purchaser shall in the course
      of carrying out such due diligence as Purchaser shall
      consider appropriate by way of searches, enquiries,
      inspections and title investigation and during the Interim
      Period shall notify Seller of any matter ("Relevant Property

      14 North Silver Street, Aberdeen or any one of such

      reasonably capable of remedy) at its expense use its best
      endeavours to remedy the same and in any event clause 7.6(b)
      to (e) (inclusive) shall apply mutatis mutandis save that

      provided that this clause shall not apply in respect of any
      matter relating to the design or construction of any

             Purchaser, the Company or the Subsidiaries in respect
             of such Obligations.  Furthermore, Purchaser shall keep
             Seller fully informed of all material developments in
             respect of any matter which relates to or is likely to
             relate to any of the indemnities provided in clauses
             6.3, 6.4 and 6.5 (including, without limitation, the
             terms of any proposed settlement of the latter); 

      (b)    if any Benefits in respect of the Excluded Lease or the
             Relevant Disputes and Agreements are received by,
             credited to or enjoyed by Purchaser or the Group,
             Purchaser shall notify Seller accordingly and Purchaser
             shall pay to Seller (subject to paragraph (c) below)
             amounts equal to and in respect of such Benefits (after
             deducting all costs and expenses reasonably and
             properly incurred in obtaining the Benefits); and

      (c)    the provisions of clause 3.3(b) and 3.3(c) shall apply
             mutatis mutandis in relation to all Obligations and
             Benefits referred to in this clause 6.6 as they apply
             in relation to amounts referred to in clause 3.3(a). 

6.7   (a)    Any amount to be paid in accordance with clauses 6.3,
             6.4 or 6.5 shall be paid within fourteen days of
             receipt thereof (in the case of Benefits) (or, in the
             case of Obligations, within fourteen days of receipt of
             notification from the relevant indemnified Party that
             it (or (if relevant) any member of the Group) has
             incurred such Obligations) to a bank account nominated
             by the relevant indemnified Party.

      (b)    Interest shall accrue on amounts due and payable under
             this clause 6.7 which remain unpaid at the expiry of
             the fourteen day payment period at the rate of 3 per
             cent per annum over the Agreed Rate from the day
             following the expiry of such fourteen day period until
             the date of payment.

      (c)    Without prejudice to paragraphs (a) and (b) above, if
             any dispute arises over whether any amount is payable
             pursuant to clause 6.3, 6.4 or 6.5 and such dispute has
             not been resolved within sixty days of the date of the
             first written notice that such a dispute exists, then
             either party may at any time thereafter refer the
             matter for determination by a firm of independent
             chartered accountants, and the principles set out in
<PAGE>
<PAGE> 49

             clause 3.7 shall apply, mutatis mutandis, in respect of
             their appointment and their determination of the
             matter.

      (d)    If any amount paid or due to Purchaser under this
             clause 6 is a taxable receipt of Purchaser then the
             amount so paid or due (the "Net Amount") shall be
             increased to an amount which, after subtraction of the
             amount of any Taxation on such increased amount which
             arises, shall equal the Net Amount provided that if any
             payment is initially made on the basis that the amount
             due is not taxable in the hands of Purchaser and it is
             subsequently determined that it is, or vice versa, such
             adjustment shall be made between Purchaser and Seller
             as may be required.

      (e)    Where any amount payable by Seller or by Purchaser (as
             the case may be) pursuant to clauses 6.3, 6.4 or 6.5
             relates to an item which can or should be taken into
             account as a deduction or receipt in computing any
             liability to Taxation of the Company or any one of the
             Subsidiaries (but, in relation to corporation tax on
             chargeable gains, only in relation to the disposals the
             subject of clauses 6.3, 6.4 or 6.5 and only to the
             extent that the computation produces a chargeable gain
             or allowable loss), the same shall be reduced by the
             percentage equal to the applicable percentage rate of
             Taxation (not being, in the case of Corporation Tax,
             the small companies' rate) for the relevant accounting
             period in which the amount in question becomes payable
             or receivable (irrespective of whether that is a period
             for which tax payable by the Company or Subsidiary is
             in fact reduced or increased by reference to the item
             or the amount payable or receivable, and irrespective
             of the availability of any other reliefs or
             allowances).  In relation to whether the provisions of
             this clause 6.7(e) apply:

             (i)      the Purchaser agrees to procure that, unless
                      Seller otherwise agrees in writing, the Group
                      shall prepare and submit any computations and
                      returns required for the purposes of the Group's
                      Taxation affairs as if they did so apply; and

             (ii)     in the event that any Taxation Authority queries
                      whether they do so apply, the provisions of
                      clause 5 of the Deed of Tax Indemnity shall
                      apply as if such query were a Claim (as defined
                      in the Deed of Tax Indemnity).

      (f)    If pursuant to clause 6.7(e) it has initially been
             assumed that an amount can or then should so be taken
             into account as a deduction or receipt and subsequently
             it is finally determined not to be a deduction or
             receipt in computing any liability to Taxation of the
             Company or any one of the Subsidiaries, Seller shall
             promptly pay to Purchaser an amount equal to the amount
             by which the relevant item had been previously reduced.

             If pursuant to clause 6.7(e) it has initially been
             assumed that an amount cannot or should not be taken
             into account as a deduction or receipt and subsequently
             it is finally determined to be a deduction or receipt
             in computing any liability to Taxation of the Company
             or a Subsidiary, Purchaser shall promptly pay to Seller
             an amount equal to the amount by which the relevant
             item would have been so reduced, if it had been
             initially assumed to be a deduction or receipt.

      (c)    Seller shall procure that Company shall pay to the

             or sums as the Company shall be obliged under the
             contracts of employment of such Employees to pay to
             such Employees by way of retention bonus and Seller

             contractual obligation to pay any such bonus.  Seller
             represents that the names of each of the Employees
             entitled to such bonus and the amounts payable to each
             of them are specified in Schedule 6;

      (d)    Seller shall terminate, or shall procure the
             termination of, on or before Completion the Company's
             and any Employee's participation in the Group Long Term
             Disability Insurance Scheme and/or and/or the Share
             Purchase Plan and/or the Private Medical Insurance
             Scheme and any other scheme, plan or other arrangement
             (excluding the Pension Scheme) for the provision of any
             non-cash benefit to any Employee and Seller shall be
             responsible for and shall hold harmless and indemnify
             and keep indemnified Purchaser and any member of the
             Group in respect of all and any Obligations arising
             directly or indirectly out of or in connection with
             such scheme or schemes and/or plan and/or arrangement,
             or their termination, or cessation of participation by
             the Company or any Employee therein, including for the
             avoidance of doubt all and any obligations arising
             directly or indirectly in relation to any Employees who
             may from time to time have been, or be entitled, to
             receive any benefit under such scheme or schemes and/or
             plan and/or arrangement.

      (e)    Seller shall be liable for and shall indemnify and keep
             indemnified Purchaser and the Group in respect of all
             Obligations arising out of any liability incurred by
             the Company under the indemnity contained in paragraph
             9 of Appendix 5 of the Brown & Root Agreement;

      (f)    Where any amount payable by Seller pursuant to this
             clause 6.8 relates to an item which can or should be
             taken into account as a deduction or receipt in
             computing any liability to Taxation of the Company or a
             Subsidiary (but, in relation to corporation tax on
             chargeable gains, only to the extent that the
             computation produces a chargeable gain or allowable
             loss), the same shall be reduced by the percentage
<PAGE>
<PAGE> 52

             equal to the applicable percentage rate of Taxation
             (not being, in the case of Corporation Tax, the small
             companies' rate) for the relevant accounting period in
             which the amount in question becomes payable or
             receivable (irrespective of whether that is a period
             for which tax payable by the Company or Subsidiary is
             in fact reduced or increased by reference to the item
             or the amount payable or receivable, and irrespective
             of the availability of any other reliefs or
             allowances). If pursuant to this clause 6.8(f) it has
             initially been assumed that an amount can or then
             should so be taken into account as a deduction or
             receipt and subsequently it is finally determined not
             to be a deduction or receipt in computing any liability
             to Taxation of the Company or any one of the
             Subsidiaries, Seller shall promptly pay to Purchaser an
             amount equal to the amount by which the relevant item
             had been previously reduced.

             If pursuant to this clause 6.8(f) it has initially been
             assumed that an amount cannot or should not be taken
             into account as a deduction or receipt and subsequently
             it is finally determined to be a deduction or receipt
             in computing any liability to Taxation of the Company
             or a Subsidiary, Purchaser shall promptly pay to Seller
             an amount equal to the amount by which the relevant
             item would have been so reduced, if it had been
             initially assumed to be a deduction or receipt.

      (g)    Purchaser will procure that the Company will provide
             all reasonable assistance and take any requisite action
             to enable Seller to comply with its obligations under
             sub-clauses (b), (c), (d) and (e) above and will
             procure that the Company will permit Seller to have
             reasonable control over dealing with any claims in
             respect of which Purchaser and the Group has the
             benefit of Seller's indemnity in sub-clauses (b), (c),
             (d) and (e) above.

      (h)    (i)      Seller undertakes to Purchaser for its own
                      benefit and as trustee and agent for the Company
                      to indemnify and to keep indemnified and to hold
                      harmless on a continuing basis the Purchaser and
                      the Company against all and any liabilities,
                      actions, claims and reasonable costs (including
<PAGE>

                      reasonable legal expenses) which may be brought
                      or made against or incurred by the Company
                      and/or the Purchaser of any nature arising out
                      of or in connection with:

                      (A)       the Pension Scheme (including, but

                                the foregoing, the costs of the winding
                                up of the Pension Scheme) other than any
                                such liability, action, claim and cost
                                which arises as a result of any wilful
                                default after Completion of the Company;

                                Provisions) to the Brown & Root
                                Agreement.

             (ii)     to the extent that the Company has any rights,
                      powers and discretions under the Pension Scheme,
                      Purchaser shall following Completion procure
                      that, subject to Seller complying with the above
                      paragraph, the Company exercises or refrains
                      from exercising any and all its rights, powers
                      and discretions under the Pension Scheme as
                      Seller may from time to time reasonably request.

             (iii)    subject to (ii) above Seller shall:

                      (aa)      procure that prior to Completion the
                                Trustees shall be changed so as to be
                                Michael Allen and/or such other Trustees
                                as the Seller may nominate (other than
                                the Purchaser or the Company);

                      (bb)      procure that prior to Completion the
                                provisions of the Pension Scheme shall
                                be amended (subject to the agreement of
                                the Trustees) so that:

                                (A)   all rights, powers and discretions
                                      of the Company under the Pension
                                      Scheme shall be exercisable by the
                                      Trustees instead of the Company
                                      provided that no such exercise of
                                      rights, powers and discretions can
                                      or may impose any additional
                                      obligations (whether actual or
                                      contingent) on the Company;

                                      Scheme shall be met out of the
                                      assets of the Pension Scheme; and

                                (C)   no new participating employers or
                                      members shall be admitted to the

                      (cc)      shall use its reasonable endeavours to
                                procure that the Trustees shall wind up
                                the Pension Scheme as soon as reasonably
                                practicable and with effect from
                                Completion in accordance with its
                                provisions and on the basis that all its
                                assets shall be used for the benefit of
                                its members to the extent not required
                                to meet the Trustees' expenses and
                                remuneration.

             shall timely and properly file the Form, together with
             all required attachments, with the appropriate IRS
             office or offices and each shall furnish the other
             Party with a true and correct copy of the Form as and
             when filed.  Seller shall pay any and all Federal
             income taxes resulting from the Election.

      (b)    Seller and Purchaser agree that the Consideration and
             liabilities of Purchaser (plus other relevant items)
             will be allocated to the assets of the Group for all
<PAGE>
<PAGE> 55

             United States federal, state, county or local
             government tax purposes as shown in the Allocation
             Schedule attached hereto as Schedule 11.  Seller,
             Purchaser and the Group will file all federal or any
             state, county or local government Tax Returns as
             defined in paragraph 1 of Schedule 12 (including
             amended returns and claims for refund) and information
             reports in a manner consistent with such allocation.

6.10  United States Federal, State and Local Taxes
      --------------------------------------------

      The provisions of Schedule 12 shall have effect in relation
      to any Tax as defined in paragraph 1(a) of Schedule 12.

6.11  Audit and other adjustments
      ---------------------------

      (a)    Without prejudice to the provisions of clause 6.3, any
             Benefits or Obligations (including the cost of any
             audit) accruing in respect of the Licence Interests in
             the form of amounts receivable or payable by the
             Company or SONSL resulting from an audit pursuant to a
             JOA or UOA or from any other subsequent adjustment in
             relation to the operation of and expenditure
             attributable to the Licence Interests in the period
             prior to the Economic Date shall accrue to Seller and
             in the period after the Economic Date shall accrue to
             Purchaser, and accordingly Seller shall indemnify
             Purchaser against any such Obligations, and Purchaser
             shall account to Seller in respect of such Benefits,
             and in determining the amount so due by Seller or
             Purchaser the provisions of clause 3.3(b) shall apply
             in relation to the Obligation or Benefit as it applies
             in relation to an amount referred to in clause
             3.3(a)(i).

      (b)    Where any such audit takes place after the Completion
             Date, Purchaser shall use all reasonable endeavours to
             enable Seller to make representations directly to any
             relevant Operator and shall in any event be obliged to
             take account of Seller's representations in connection
             with such audit and shall notify Seller of any audit
             adjustment as soon as practicable after the results of
             such audit are known.  

      (c)    If as a result of any audit adjustment or otherwise,
             either Seller or Purchaser is liable to pay any amount
             to the other, then, to the extent that the amount
<PAGE>
<PAGE> 56

             referred to in clause 3.1 has not already been adjusted
             pursuant to the provisions of clause 3 in respect
             thereof, or the amount has not otherwise been paid in
             accordance with clause 6.3, such amount shall be paid
             to the relevant Seller's Account or the relevant
             Purchaser's Account (as appropriate) within thirty
             Business Days after the amount receivable or payable as
             a result of such an audit or other subsequent
             adjustment has been taken into account by the relevant
             Operator in the Operator's billing statement.

6.12  Any payment made under any indemnity contained in this
      clause 6 shall be treated by Purchaser as far as possible as
      a reduction or increase in the Consideration.

6.13  If at any time any applicable law, regulation or regulatory
      requirement requires Purchaser to make any deduction or
      withholding from any payment made in respect of any amount
      due from Purchaser hereunder, the amount so due shall be
      increased to the extent necessary to ensure that, after the
      making of such deduction or withholding, Seller receives, on
      the due date for such payment, a net sum equal to the sum
      which it would have received had no such deduction or
      withholding been required to be made.

6.14  If Purchaser is required by law to make any deduction or
      withholding as referred to in clause 6.13 above, Purchaser
      shall:

      (a)    make such deduction or withholding;

      (b)    pay the full amount deducted or withheld to the
             relevant authority in accordance with applicable law;
             and

      (c)    forthwith furnish to Seller the original, or a
             certified copy, of a receipt evidencing payment
             thereof.

6.15  If, following any such deduction or withholding from any
      payment by Purchaser as is referred to in clause 6.13,
      Seller shall receive or be granted a credit against or
      remission for any Taxation payable by it, Seller shall,
      subject to Purchaser having made any increased payment in
      accordance with clause 6.13 and to the extent that Seller
      can do so without prejudicing the retention of the amount of
      such credit and without prejudice to the right of Purchaser
      to obtain any other Relief (as that term is defined in the
<PAGE>
<PAGE> 57

             Deed of Tax Indemnity) which may be available to it,
             reimburse Purchaser with such amount as Seller shall
             (acting in good faith) certify to be such portion of
             such credit as will leave Seller (after such
             reimbursement) in no worse a position than it would
             have been had there been no such deduction or
             withholding from the payment by Purchaser as aforesaid. 
             Such reimbursement shall be made forthwith upon Seller
             certifying that the amount of such credit has been
             received by it.

6.16  Proposed Reorganisation
      -----------------------

      In relation to any Proposed Reorganisation:

      (a)    to the extent that Seller's liability under this
             Agreement or under the Deed of Tax Indemnity to make
             to, (or the ability to receive any payment from),
             (whether by way of set off or otherwise), Purchaser,
             the Company or the Subsidiaries arises, or is increased
             or is decreased as a result of any proposals or
             arrangements or acts (whether implemented or not) in
             relation to any Proposed Reorganisation, such
             liability, ability, increase or decrease shall be
             ignored;

      (b)    Purchaser shall not and shall procure that the Company
             or the Subsidiaries shall not file any notice, claim,
             surrender, election with any Taxation Authority or
             revoke, withdraw, amend or otherwise alter such notice,
             claim, surrender or election without Seller's consent
             in writing if such notice, claim, surrender or election
             (or such revocation, withdrawal, amendment or
             alteration) could affect the liability to  Taxation of
             Seller, the Company or any of the Subsidiaries prior to
             Completion.

6.17  Advance Corporation Tax
      -----------------------

      In relation to any advance corporation tax in respect of any
      distribution made prior to the Completion Date which has not
      been estimated in the Accounts as recoverable against any
      liability of the Group to corporation tax for periods up to
<PAGE>
<PAGE> 58

      and including the Economic Date ("Surplus ACT"), Purchaser
      agrees:

      (a)    to the extent that such Surplus ACT is later found to
             be capable of being set-off against any liability of
             the Group to corporation tax for such periods that it
             will procure that such claims are made as are required
             in order for such set-off to be effective and that if
             any such action gives rise to a repayment of
             corporation tax, it will account to Seller for an
             amount equal to such repayment (together with any
             associated interest or repayment supplement);

      (b)    to the extent that (a) does not apply that it will
             account to Seller for an amount equal to any such
             Surplus ACT which is capable of set-off against any
             liability of a member of the Group to corporation tax
             for accounting periods commencing on or after the
             Economic Date on the earlier of the date on which the
             benefit of such set-off is recognised in the tax
             computations prepared by such member and the date on
             which such set-off gives rise to a reduction in the
             liability to pay any amount in respect of corporation
             tax for such accounting period;

      (c)    if payment has been made by Purchaser under either (a)
             or (b) above and subsequently it is finally determined
             that the relevant Surplus ACT is incapable of set off
             by reason of an act or omission of Seller or Seller
             Group or the Group on or before Completion, Seller
             shall promptly repay to Purchaser, together with
             interest at the Agreed Rate, an amount equal to the
             amount of such Surplus ACT which is so incapable of set
             off;

      (d)    if an Event (as defined in the Deed of Tax Indemnity)
             occurs or is deemed for Taxation purposes to occur on
             or after Completion in relation to any member of the
             Group, which renders such Surplus ACT incapable of set
             off which would otherwise have been so capable,
             Purchaser shall be under no obligation to Seller under
             (a) or (b) but any liability of Seller under the Deed
             of Tax Indemnity shall be reduced by an amount equal to
             the payment that would otherwise have been made; and

      (e)    in calculating any liability of Seller or Purchaser to
             make any payment under this clause 6.17, the provisions
             of clause 6.16 shall be ignored.

7     Representations and Warranties
      ------------------------------

7.1   Subject to the provisions of this clause 7 and save as fully
      and fairly disclosed under the terms of the Disclosure
      Letter, Seller hereby represents, warrants and undertakes to
      Purchaser that each of the warranties set out in Part II of
      Schedule 3 is true and accurate in all respects and not
      misleading at the date of this Agreement.  For the purposes
      of this clause 7 and the Disclosure Letter "fully and fairly
      disclosed" means disclosed in such manner and such detail as
      to enable Purchaser to make an informed and materially
      accurate assessment of the matter concerned.  

7.2   Subject to the provisions of this clause 7 and save as
      otherwise expressly disclosed in writing to Seller,
      Purchaser hereby represents, warrants and undertakes to
      Seller that each of the warranties set out in Part I of
      Schedule 3 is true and accurate in all respects and not
      misleading at the date of this Agreement.

7.3   Neither Party shall do any act or thing, or authorise any
      act or thing to be done over which it has control or which
      it can otherwise by the exercise of any right or power
      reasonably prevent from being done, which would prevent any
      representation, warranty or undertaking given by it above
      from being true and accurate in all material respects if the
      same were to be repeated at the Completion Date by reference
      to circumstances then existing.

7.4   Seller shall promptly notify Purchaser in writing of any
      circumstances or facts, omission or matters which (whenever
      arising) become known to it or any member of the Group prior
      to Completion which are or are reasonably likely to be
      inconsistent in any material respect with any of the
      representations and warranties referred to in clause 7.1 (or
      which would be so inconsistent were such representations and
      warranties to be repeated each day from the date hereof to
      the Completion Date).  Such notice shall state that it is
      served pursuant to this clause 7.4.  This clause 7.4 shall
      apply mutatis mutandis in the event of any circumstances or
      facts or matters which (whenever arising) become known to
      Purchaser prior to Completion which are inconsistent in any
      material respect with the representations and warranties
      referred to in clause 7.2 (or which would be so inconsistent
      were such representations and warranties to be repeated each
      day from the date hereof to the Completion Date).
<PAGE>
<PAGE> 60

7.5   Each of the representations and warranties contained in this
      Agreement shall be construed as a separate and independent
      warranty and (except where expressly provided to the
      contrary) shall not be limited or restricted by reference to
      or inference from the terms of any other representation or
      warranty contained herein or any other term of this
      Agreement.

7.6   In the event that any circumstance, fact or matter is
      notified by Seller in accordance with clause 7.4 above which
      would, if the same were to subsist or be repeated at
      Completion, be inconsistent with Seller's representations
      and warranties as aforesaid (an "Inconsistency") or
      Purchaser becomes aware of an Inconsistency and so notifies
      Seller, then:

      (a)    if the Inconsistency is capable of remedy, Seller shall
             use its best endeavours to remedy the same at its own
             expense as soon as practicable;

      (b)    if the Inconsistency has not been so remedied at the
             time set for Completion to the reasonable satisfaction
             of Purchaser or if the same is incapable of remedy, the
             Parties shall discuss the effects on the value of the
             business and assets of the Group and whether the terms
             hereof could be amended to take account of any such
             change in circumstance, fact or matter;

      (c)    in the absence of agreement between the Parties as to
             such amendment, and PROVIDED THAT the adverse effect of
             all Inconsistencies which have not been remedied or are
             incapable of being remedied on the value of the
             business and assets of the Group exceeds $29,100,000
             Purchaser shall not be obliged to complete the
             acquisition of the Sale Shares and shall be entitled by
             notice in writing to Seller given at any time prior to
             Completion to terminate this Agreement.  In the
             circumstances contemplated by paragraphs (a) to (c),
             termination shall, save as provided in paragraph (e),
             be Purchaser's only remedy and, if this Agreement is so
             terminated, Seller shall have no further liability to
             Purchaser with respect to or in connection with such
             Inconsistencies; and

      (d)    subject to paragraph (c) and PROVIDED THAT the adverse
             effect of all such Inconsistencies on the value of the
             business and assets of the Group exceeds $2,900,000,
             Purchaser shall be obliged to complete the acquisition
<PAGE>
<PAGE> 61

             of the Sale Shares but without prejudice to its right
             to claim damages in respect of such Inconsistencies, in
             which event the provisions of clauses 7.13 to 7.22
             shall apply mutatis mutandis; and

      (e)    where Purchaser terminates this Agreement under this
             clause 7.6 the provisions of clause 10.3 shall apply.

      This clause 7.6 shall apply mutatis mutandis in the event of
      any circumstance, fact or matter notified by Purchaser in
      accordance with clause 7.4.

7.7   Not used.

7.8   Save as and only to the extent set forth in clause 7.1, or
      as the case may be clause 7.2 neither of the Parties makes
      any representations or warranties in respect of any matter
      or thing and disclaims all liability and responsibility for
      any representation, warranty, statement, opinion or
      information made or communicated (orally or in writing) to
      the other (including, without limiting the generality of the
      foregoing, any representation, warranty, statement, opinion,
      information or advice made and communicated to Purchaser by
      any officer, stockholder, director, employee, agent,
      consultant or representative of Seller or its agents or any
      of their respective Affiliates) and Purchaser acknowledges
      and affirms that it has not relied upon any such
      representation, warranty, statement, opinion or information
      in entering into or carrying out the transactions
      contemplated by this Agreement or any of them.  Without
      limiting the generality of the foregoing, Seller makes no
      representations or warranties as to (a) the amounts of
      Petroleum reserves attributable to the Licence Interests, or
      (b) any geological, geophysical, engineering, economic or
      other interpretations, forecasts or evaluations.  

7.9   Seller shall not be liable for any claim in relation to
      breach of the representations and warranties given by Seller
      unless it shall have received from Purchaser written notice
      thereof given on or before the expiry of 30 months following
      the Completion Date, Provided that in respect of claims made
      under Warranties relating to Taxation, or any claim under
      the Deed of Tax Indemnity, the last date for written notice
      of such claiming shall be the seventh anniversary of the
      Completion Date.  Any claim made shall be deemed to have
      been withdrawn unless proceedings in respect thereof have
      been both issued and served on Seller within 12 months of
      the giving of such notice.  Purchaser undertakes to give the
<PAGE>
<PAGE> 62

      Seller written notice as soon as practicable after it
      becomes aware of a breach of warranties and representations
      by Seller together with reasonable details of the relevant
      claim including its provisional estimate (on a non-binding
      and without prejudice basis) of the amount of such claim.

7.10  Seller acknowledges that Purchaser has entered into this
      Agreement in reliance on the representations undertakings
      and warranties of Seller referred to herein.

7.11  Purchaser shall not be liable for any claim in relation to
      breach of the representations and warranties unless it shall
      have received from Seller, as soon as practicable after
      Seller becomes aware of the same, written notice containing
      reasonable details of the relevant claim including Seller's
      provisional estimate of the amount of the claim and in any
      event such notice is received on or before the expiry of 30
      months following the Completion Date.

7.12  The liability of Seller under or in respect of the
      Warranties given by it, the Deed of Tax Indemnity, Schedule
      12 and the indemnities set out in clause 6 shall be limited
      as follows:

      (a)    there shall be disregarded for all purposes any claim
             for a breach of Warranty in respect of which the amount
             of the damages or indemnity payment to which Purchaser
             would otherwise be entitled is less than $200,000 (two
             hundred thousand Dollars);

      (b)    Seller shall have no liability for breaches of Warranty
             except to the extent that the damages to which
             Purchaser is entitled in aggregate exceed $2,000,000
             (two million Dollars) and to the extent that they do
             exceed that sum, the full amount shall be recoverable
             and not merely the excess;

      (c)    The liability of Seller under or in respect of the Deed
             of Tax Indemnity and Schedule 12 shall not be subject
             to clause 7.12(a) and (b) Provided that Seller shall
             not be liable to make the first payment under the Deed
             of Tax Indemnity or Schedule 12 until the aggregate
             amount of such payments is $250,000 or more Provided
             Further that once such aggregate amount is reached, the
             whole amount shall become payable and thereafter Seller
             shall make payments in respect of claims under the Deed
             of Tax Indemnity or Schedule 12 as they fall due from
             time to time and if at the end of the period of seven
             years referred to in clause 7.9 the aggregate liability
<PAGE>
<PAGE> 63

             of Seller under or in respect of the Deed of Tax
             Indemnity and Schedule 12 shall be less than $250,000
             the whole of such aggregate amount shall nevertheless
             be payable.

      (d)    for the purpose of sub-clause 7.12(a) where a number of
             claims arise directly from the same event,
             circumstance, fact or matter, such claims shall be
             treated as a single claim in respect of such event,
             circumstance, fact or matter; and

      (e)    the maximum aggregate liability of Seller in respect of
             all claims for breach of Warranty or under the Tax
             Indemnity or Schedule 12 or under paragraphs (ii) to
             (viii) of clause 6.5 shall not exceed an amount equal
             to the Consideration.  For the avoidance of doubt, save
             as provided in this paragraph (e), none of the
             limitations set out in this clause 7.12 shall apply to
             any indemnity given by Seller under this Agreement.  

7.13  If: 

      (a)    Purchaser becomes aware of any breach of Warranty by
             Seller which may result in Purchaser having a claim
             against Seller under this clause 7 as a result of or in
             connection with a liability or alleged liability to a
             third party, or

      (b)    Purchaser or the Company or the Subsidiaries is or may
             be entitled to recover from some other person, firm,
             authority or body corporate any sum in respect of which
             Purchaser may have a claim against Seller under the
             Warranties, 

      Purchaser shall as soon as practicable notify Seller thereof
      in writing and Seller shall be entitled (i) to take and/or
      require Purchaser to take any action Seller might reasonably
      request to resist such liability or enforce (or ensure the
      enforcement of) such recovery (in each case, in the name of
      Purchaser (or the Company or the Subsidiaries, as the case
      may be) but at the cost and expense of Seller and subject to
      an indemnity in respect of such cost and expense any other
      liability which Purchaser, the Company or Subsidiaries may
      incur as a result of and any liability or obligation which
      Purchaser, the Company or the Subsidiaries would not have
      incurred but for any action taken by Purchaser or at his
      direction pursuant to this paragraph to be given to
      Purchaser the Company or the Subsidiaries in a form
<PAGE>
<PAGE> 64

      reasonably required by Purchaser), and (ii) at its own cost
      and expense to have conduct of any appeal, dispute,
      compromise or defence of the dispute and of any incidental
      negotiations for the aforesaid purposes, and Purchaser will
      (and will ensure that the Company or the Subsidiaries, as
      the case may be, will) give Seller all co-operation, access
      and assistance for the purposes of resisting such liability
      or enforcing such recovery (as the case may be) as Seller
      may reasonably require unless Purchaser reasonably considers
      that any step proposed under this paragraph will cause
      costs, loss or liability to it or the Company or the
      Subsidiaries which the indemnity to be provided under this
      paragraph will not cover in full.

7.14  If Seller pays to Purchaser an amount pursuant to a claim in
      respect of the representations and warranties and Purchaser
      is entitled to recover from some other person any sum to
      which it would not have been or become entitled but for the
      circumstances giving rise to such a claim, Purchaser shall
      promptly take such reasonable action as Seller may require
      to enforce such recovery but always at the cost and expense
      of Seller and subject to an indemnity covering the same
      matters as in clause 7.13 above and shall as soon as
      practicable repay to Seller so much of the amount paid by it
      as equals the amount recovered from the third party, less
      all costs, charges and expenses reasonably incurred by
      Purchaser in obtaining that payment and in recovering that
      amount from the third party.  This clause shall apply
      mutatis mutandis in favour of Purchaser where Seller is
      entitled to recover from some other person.

7.15  Seller shall not be liable for breach of any of the
      representations and warranties, nor shall Purchaser have any
      rights in respect of any inconsistency therewith arising
      after the date hereof, to the extent only that such breach
      or inconsistency is occasioned by Seller doing or omitting
      to do any act or thing at the written request of or with the
      prior written agreement of Purchaser in accordance with
      clause 4 during the Interim Period.

7.16  No liability shall arise on the part of Seller to Purchaser
      in respect of any breach of any of the Warranties if and to
      the extent that:

      (a)    any breach or claim occurs as a result of any
             legislation coming into force after the date hereof
             which takes effect retrospectively or the amount
             recoverable in respect thereof is increased as a result
<PAGE>
<PAGE> 65

             of any Taxation legislation, withdrawal of or change in
             administrative practice or Taxation Authority
             concessions coming into force after the date hereof
             which takes effect retrospectively, or judicial
             decision on any point inconsistent with the basis on
             which the Company or the Subsidiary in question has
             previously prepared and filed computations and returns,
             or occurs or is increased as a result of any increase
             in the rate of Taxation coming into force after such
             date or occurs as a result of or is otherwise
             attributable to Purchaser, an Affiliate of Purchaser,
             or the Company or the Subsidiaries disclaiming any part
             of the benefit of capital or other allowances against
             Taxation claimed on or before the date hereof or
             proposed to be claimed (information in relation to such
             proposed claims having been provided to Purchaser in
             writing under the terms of the Disclosure Letter, and
             the amounts the subject of the same to be notified in
             writing to Purchaser), or omitting to make or revising
             or withdrawing any such claim or any election or
             surrender or doing (or omitting to do) any other thing
             in circumstances where the same affects the treatment
             of any relief against Taxation taken into account in
             the preparation of the Net Working Capital Statement or
             claimed on or before the date hereof or proposed to be
             claimed (provided that information in relation to such
             reliefs or proposed claims has been provided to the
             Purchaser in writing on or prior to Completion, and the
             amounts the subject of the same are notified in writing
             to the Purchaser);

      (b)    any such breach or claim consists of a claim for
             Taxation for which the Company or any of the
             Subsidiaries is primarily liable arising as a result of
             transactions in the ordinary course of business of the
             Company or the Subsidiaries after the Economic Date
             (save insofar as such Taxation relates to the Excluded
             Lease);

      (c)    the breach or claim relates to a claim or liability for
             Taxation which would not have arisen but for any
             winding-up or cessation of any trade or business
             carried on by the Company or the Subsidiaries or change
             in their respective accounting policies or practices
             after Completion other than, in the case of any such
             accounting policies or practices which do not accord
             with Generally Accepted UK Accounting Principles as
             they are in force at the date hereof, to bring them
             into line with such principles;
<PAGE>
<PAGE> 66

      (d)    the breach or claim relates to a claim or liability for
             Taxation which is stamp duty or stamp duty reserve tax
             imposed as a result of or in consequence of the
             purchase of the Sale Shares;

      (e)    the amount for which Seller is liable under the
             Warranties does not exceed an amount in respect of the
             same matter for which Seller is liable under the Deed
             of Tax Indemnity, and such liability has been fully
             satisfied;

      (f)    the breach or claim would not have arisen but for any
             act voluntarily effected after Completion by Purchaser,
             the Company or the Subsidiaries otherwise than pursuant
             to a legally binding commitment created on or before
             Completion and otherwise than in the ordinary course of
             business and which Purchaser, an Affiliate of Purchaser
             having an interest in the shares of the Company or
             Subsidiary, or the Company or Subsidiary knew (or would
             have known if it had made all reasonable enquiries)
             would give rise to the liability in question;

      (g)    a payment has been made in respect of such breach or
             claim pursuant to clause 6; or

      (h)    a liability in respect of a breach or claim has
             operated to reduce the Consideration, pursuant to
             clause 3.

7.17  Nothing in this Agreement shall relieve Purchaser of any
      common law duty to mitigate any loss or damage incurred by
      it in respect of any breach of the Warranties or any other
      term of the Agreement.

7.18  If Seller has paid an amount in respect of any claim for
      breach of any of the Tax Warranties and Purchaser, the
      Company or the Subsidiaries shall recover a sum in respect
      of the matter giving rise to the claim or shall receive a
      Taxation credit or benefit in consequence of such claim or
      breach, Purchaser shall make a repayment to Seller, and in
      respect of such repayment clause 4 of the Deed of Tax
      Indemnity shall apply with only the necessary changes.

7.19  Purchaser shall not be entitled to recover from Seller the
      same sum or loss more than once in respect of any claims for
      breach of any Warranties.
<PAGE>
<PAGE> 67

7.20  No breach of Warranty or any covenant or undertaking in this
      Agreement shall give rise to any right on the part of
      Purchaser to rescind or terminate this Agreement following
      Completion.

7.21  Where a Warranty is qualified by the words "so far as Seller
      is aware", or any similar expression, Seller acknowledges
      that it has represented to Purchaser that such Warranty has
      been so qualified after due enquiry of directors and senior
      managers within the Seller Group and the Group by Seller,
      and that Seller has used all reasonable endeavours to ensure
      that the statement contained in that Warranty is accurate.

7.22  Any payment made by Seller in respect of any breach of
      Warranty shall be treated by Purchaser as far as possible as
      a reduction to the Consideration.

8     Announcements
      -------------

8.1   Seller and Purchaser shall jointly plan and co-ordinate the
      initial press releases and initial public announcements
      regarding this Agreement and the text of any such release or
      announcement shall be subject to the prior written consent
      of Seller and Purchaser.  The foregoing shall not apply to
      the extent that it is necessary for that Party or its
      Affiliate to make such public announcement or statement in
      order to comply with a statutory obligation, an obligation
      to include information in published or audited accounts, or
      with the requirement of a competent government agency, the
      Securities and Exchange Commission or other regulatory body,
      or a recognised stock exchange on which that Party or such
      Affiliate has its shares or oil production or royalty stock
      listed, in which event the Party proposing to make such an
      announcement or statement shall ensure that the announcement
      contains only such information as is required by the
      applicable regulations and no further information (unless
      the other Party so agrees) and, where reasonably
      practicable, issue a copy thereof to the other Party prior
      to its release and if not so practicable as soon as possible
      thereafter.

9     Notices

             expenses of the professional advisers to Purchaser
             (including, but not limited to, the fees of its

             expenses) and any irrecoverable value added tax
             thereon, incurred by Purchaser:-

             terminate, or not to proceed to Completion of, this
             Agreement pursuant to clause 7.6 and either (i) such
             termination shall have arisen as a result of the
             failure by Seller to remedy an Inconsistency which was
             capable of remedy or (ii) if such Inconsistency was not
             capable of remedy, such Inconsistency arose as a result
             of some act, omission or default of Seller, the Company
             or any Subsidiary or (bb) Purchaser shall exercise its
             right to terminate this Agreement pursuant to clause

      irrevocably submit to the non-exclusive jurisdiction of the

14.2  Seller irrevocably waives (and irrevocably agrees not to
      raise) any objection which it may have now or hereafter to
      the laying of the venue of any Proceedings in the English
      courts and any claim that any such Proceedings have been
      brought in an inconvenient forum and further irrevocably
      agrees that a judgment in any Proceedings brought in any
      English court shall be conclusive and binding upon Seller
      and may be enforced in the courts of any other jurisdiction.

15    Agent for Service

15.1  Seller irrevocably agrees that any Service Document may be
      sufficiently and effectively served on it in connection with
      Proceedings in England and Wales by service on its agent
      Norose Notices Limited, if no replacement agent has been
      appointed and notified to Purchaser pursuant to clause 15.4,
      or on the replacement agent if one has been appointed and
      notified to Purchaser.

15.2  Any Service Document served pursuant to this clause shall be
      marked for the attention of:-

      the Company.

11.4  No warranty claim has been made by or (if applicable)
      against the Company and so far as Seller is aware, there are

      right by the Company to make a warranty claim against the
      relevant contracting parties or (if applicable) vice versa
      in respect of the following:

      (a)    the Sale and Purchase Agreement dated 22 March 1994

WHEREAS this Deed is entered into pursuant to an agreement of

purchase of the issued share capital of the Company ("the
Agreement").

IT IS HEREBY AGREED as follows:

1     Interpretation
      --------------

1.1   Words and expressions defined in clause 1.1 of the Agreement

             document issued or action taken by or on behalf of any
             Taxation Authority or any form of self-assessment under
             the Pay and File system introduced by the Finance Act
             1990 from which it appears that any one or more of the
             Company and the Subsidiaries is subject to, or is
             sought to be made subject to, or might become subject
             to, any Taxation Liability;

      (b)    "Company" means Sun Oil Britain Limited;

      (c)    "Event" means any event, occurrence, transaction, act
             or omission (or any deemed event, occurrence,

             avoidance of doubt the sale and purchase of the shares
             in the Company pursuant to the Agreement;

      (d)    "Relief" means any loss, relief, allowance, exemption,
             set-off, deduction, credit or other relief relating to
             any Taxation or to the computation of income, profits
             or gains for the purposes of any Taxation including any
             right to repayment of Taxation;
<PAGE>
<PAGE> 116

      (e)    "the Subject Company" means such one or more of the
             Company and the Subsidiaries as shall be subject to a
             Taxation Liability;

      (f)    "Subsidiaries" means Sun Oil North Sea Limited and
             British Sun Oil Company Limited;

      (g)    "Taxation Liability" means a liability to make an
             actual payment of or of an amount in respect of
             Taxation whether or not such Taxation is also or
             alternatively chargeable against or attributable to any
             other person; and

      (h)    "unavailability" means, in relation to a Relief, the
             reduction, modification, claw-back, counteraction,
             disallowance or cancellation of or failure to obtain
             that Relief, and "unavailable" shall be construed
             accordingly.

1.3   The headings in this Deed are inserted for convenience only
      and shall be ignored in construing this Deed.  Unless the
      context otherwise requires the singular shall include the
      plural and vice versa.

2     Covenant by Seller
      ------------------

2.1   Subject to the provisions of clause 3 hereof, Seller hereby
      covenants with Purchaser to pay to Purchaser an amount or
      amounts equal to:

      (a)    any Taxation Liability of any one or more of the
             Company and the Subsidiaries arising as a result of, in
             respect of or by reference to:

             (i)   any Event occurring or deemed for the purposes of
                   any Taxation to occur on or before the Completion
                   Date; or

             (ii)  any income, profits or gains earned, accrued or
                   received or deemed for the purposes of any
                   Taxation to have been earned, accrued or received
                   on or before, or in respect of any period ending
                   on or before, the Completion Date;
<PAGE>
<PAGE> 117

      (b)    22.5 per cent. of:

             (i)   in relation to SONSL, 30 per cent. of any decrease
                   as is finally determined to be made in SONSL's
                   qualifying expenditure (as at 1st July 1996) for
                   the purposes of section 25 CAA 1990, in respect of
                   its acquisition on 4th June, 1993 of the P344
                   interest in the Balmoral Field, where such
                   decrease results solely from an adjustment being
                   finally determined by a Taxation Authority to the
                   consideration apportioned in the agreement for its
                   acquisition;

             (ii)  in relation to the Company, 49 per cent. of any
                   decrease as is finally determined to be made in
                   the Company's qualifying expenditure (as at 1st
                   July 1996) for the purposes of section 25 CAA 1990
                   in respect of its acquisition on 22nd March, 1994
                   or the P199 interest in the Ninian Field, where
                   such decrease results solely from an adjustment
                   being finally determined by a Taxation Authority
                   to the consideration apportioned in the agreement
                   for its acquisition;

      (c)    any costs and expenses payable by Purchaser or any one
             or more of the Company and the Subsidiaries in
             connection with any such liability or amount as is
             referred to in paragraph (a) or (b) above or with any
             claim in respect thereof or in taking or defending any
             action under clause 5 of this Deed.

2.2   Any payments made pursuant to clause 2.1 hereof shall, so
      far as possible, be treated as an adjustment to the
      consideration paid by Purchaser for the issued share capital
      of the Company under the Agreement.

3     Limitations
      -----------

3.1   The covenant contained in clause 2 shall not extend to any
      Taxation Liability:

      (a)    to the extent that provision, reserve or allowance has
             been made for such Taxation Liability in the Accounts; 

      (b)    to the extent that such Taxation Liability has been
             taken into account in determining the Net Working
             Capital or is the subject of a payment pursuant to
             clause 6 of the Agreement;
<PAGE>
<PAGE> 118

      (c)    for which the Company or the Subsidiaries is, or may
             become, liable as a result of any Event in the ordinary
             course of its business after the Economic Date (save
             insofar as such Taxation Liability relates to the
             Excluded Lease); 

      (d)    to the extent that such Taxation Liability was paid or
             discharged before the Economic Date;

      (e)    to the extent that such Taxation Liability arises or is
             increased as a result of any provision or reserve in
             the Accounts being insufficient by reason only of any
             increase in the rate of Taxation made or any change in
             Taxation legislation after the date of the Agreement;

      (f)    to the extent that such Taxation Liability arises or is
             increased as the result of the withdrawal or change in
             the terms of any administrative practice or Taxation
             Authority concession coming into force after the date
             of the Agreement which takes effect retrospectively or
             as a result of any judicial decision after the date of
             the Agreement on any point being inconsistent with the
             basis on which the Company or the Subsidiary in
             question has previously prepared and filed computations
             and returns;

      (g)    to the extent that such Taxation Liability arises or is
             increased as the result of any act or omission effected
             by the Company, the Subsidiaries or Purchaser after
             Completion otherwise than pursuant to a legally binding
             commitment created on or before Completion and
             otherwise than in the ordinary course of business;

      (h)    to the extent that such Taxation Liability arises as a
             result of any change on or after Completion in any
             accounting policy or practice, or any Taxation
             reporting or computation practice (including the basis
             of preparation and method of submission of any Taxation
             returns), of the Company or the Subsidiaries;

      (i)    to the extent that such Taxation Liability arises as a
             result of Purchaser, the Company or the Subsidiaries
             failing to submit the returns and computations required
             to be made by them or not submitting such returns and
             computations within the appropriate time limits or
             submitting such returns and computations otherwise than
             on a proper basis, in each case after Completion;
<PAGE>
<PAGE> 119

      (j)    to the extent that such Taxation Liability would not
             have arisen but for Purchaser, an Affiliate of
             Purchaser, or the Company or the Subsidiaries
             disclaiming any part of the benefit of capital or other
             allowances against Taxation claimed on or before the
             date hereof or proposed to be claimed (information in
             relation to such proposed claims having been provided 
             to Purchaser in writing under the terms of the
             Disclosure Letter, and the amounts the subject of the
             same to be notified in writing to Purchaser), or
             omitting to make or revising or withdrawing any such
             claim or any election or surrender or doing (or
             omitting to do) any other thing  in circumstances where
             the same affects the treatment of any relief against
             Taxation taken into account in the Accounts or in
             determining the Net Working Capital or claimed on or
             before the date hereof or proposed to be claimed
             (provided that information in relation to such proposed
             claims has been provided to Purchaser in writing on or
             prior to Completion, and the amounts the subject of the
             same are notified in writing to Purchaser);

      (k)    to the extent that such Taxation Liability arises under
             Part XV of the Value Added Tax Regulations 1995 by
             reason of any Event or change in circumstances
             occurring after Completion;

      (l)    to the extent that such Taxation Liability arises or is
             increased as a consequence of any failure by Purchaser,
             the Company or any Subsidiary to comply with any of
             their obligations under this Deed or the Agreement;

      (m)    to the extent that the amount for which Seller is
             liable under this Deed does not exceed an amount for
             which Seller is liable under the Agreement in respect
             of the same matter, and such liability has been fully
             satisfied;

      (n)    to the extent that the Company or any associated
             company of the Company has received an amount in
             respect of such Taxation Liability from any Third Party
             (as defined in clause 4 of the Deed);

      (o)    to the extent that such Taxation Liability is stamp
             duty or stamp duty reserve tax imposed as a result of
             or in consequence of the purchase of the Sale Shares;
<PAGE>
<PAGE> 120

      (p)    to the extent that a payment has been made in respect
             of such Taxation Liability pursuant to clause 6 of the
             Agreement; and

      (q)    to the extent that Seller or such other person as is
             referred to in clause 9.1(a) hereof has satisfied such
             Taxation Liability by reason of being liable for such
             Taxation under section 767A ICTA 1988.  

3.2   The provisions of clauses 6.16, 7.9 and 7.12 of the
      Agreement shall operate so as to restrict the liability of
      Seller hereunder.

4     Rebate
      ------

4.1   Purchaser undertakes that if, where Seller has paid or is
      required to pay any amount due hereunder in respect of any
      Taxation Liability, Purchaser or the Subject Company is or
      becomes entitled to receive or receives from any person
      other than the Company or any of the Subsidiaries ("the
      Third Party") a payment, credit or benefit in respect of
      such Taxation Liability, Seller shall remain liable to make
      a payment to Purchaser hereunder (except to the extent that
      such payment, credit or benefit has been received by
      Purchaser or the Subject Company prior to the due date for
      such payment by Seller), and shall make such payment in
      accordance with Clause 7, but Purchaser shall notify Seller
      of such entitlement or recovery as soon as reasonably
      practicable and, where recovery has not been effected at the
      date of notification, shall (if requested by and at the
      expense of Seller and upon Seller indemnifying the Company
      or Purchaser to its reasonable satisfaction against all
      costs or expenses which may be thereby incurred) take, or
      cause the Subject Company to take, such action as Seller
      shall reasonably request to enforce such recovery against
      the person in question (keeping Seller fully informed of the
      progress of any action taken) and Purchaser shall repay to
      Seller a sum equal to the lesser of: 

      (a)    the amount of any payment so received or the amount
             that Purchaser or the Subject Company will save by
             virtue of the credit or benefit ("the Benefit"), after
             deduction therefrom of an amount equal to any costs
             incurred in obtaining it and any Taxation Liability in
             respect of it; and

      (b)    the aggregate  amount paid by Seller hereunder in
             respect of the Taxation Liability in question.
<PAGE>
<PAGE> 121

      Any amount of the Benefit not so paid to Seller shall be
      carried forward and set off against any amount payable in
      respect of any claims hereunder.

4.2   Any payment required to be made by Purchaser and the Subject
      Company pursuant to clause 4.1 shall be made:

      (a)    in a case where Purchaser or the Subject Company
             receives a payment or a credit or benefit other than in
             the form of a Relief, within 5 business days of the
             receipt thereof; and

      (b)    in a case where Purchaser or the Subject Company
             receives a credit or benefit in the form of a Relief,
             on or before the date on which Taxation would have been
             recoverable by the appropriate Taxation Authority but
             for the use of such Relief.

4.3   Purchaser shall ensure that any such Relief as is referred
      to in clause 4.2(b) is used in priority to any other Relief,
      and in the absence of evidence to the contrary it shall be
      deemed to be so used.  Seller shall be entitled to require
      (at the expense of Seller) that the Subject Company's
      auditors shall certify the amount and date of use of such
      Relief for the purposes of this clause 4.

4.4   Any sum not paid by Purchaser or the Subject Company on the
      due date of payment specified in clause 4.2 shall bear
      interest (which shall accrue from day to day after as well
      as before any judgment for the same) at the Agreed Rate from
      the due date to and including the day of actual payment of
      such sum.  Such interest shall be paid on the demand of
      Seller.

5     Conduct of Claims
      -----------------

5.1   If Purchaser shall become aware of any Claim which is likely
      to give rise to a liability on Seller hereunder, Purchaser
      shall give notice thereof or ensure that notice thereof is
      given as soon as reasonably practicable to Seller in
      accordance with clause 9.

5.2   As regards any Claim, Purchaser shall take or shall ensure
      that the Subject Company shall take such action as Seller
      may by written notice given to Purchaser reasonably request
      to cause the Claim to be withdrawn or to dispute, resist,
      appeal against, compromise or defend the Claim and any
<PAGE>
<PAGE> 122

      determination in respect thereof or to apply to postpone (so
      far as legally possible) the payment of any tax pending the
      determination of any appeal but subject to Purchaser and the
      Subject Company being indemnified to their reasonable
      satisfaction by Seller against all losses (including any
      additional Taxation Liability), interest, costs, damages and
      expenses which may be thereby incurred by Purchaser or the
      Subject Company, and Provided that:

      (a)    any request made by Seller pursuant to this clause 5.2
             shall be made within a reasonable time of receipt by
             Seller of any notice given by Purchaser to Seller in
             accordance with clause 5.1;

      (b)    Purchaser and the Subject Company shall not be obliged
             to comply with any request of Seller which involves
             contesting any assessment for Taxation before any court
             or any other appellate body unless they have been
             advised in writing by leading tax counsel instructed by
             agreement between Purchaser and Seller at the expense
             of Seller that it is worth proceeding with an appeal
             against the assessment for Taxation.

6     Over-provision and Corresponding Savings
      ----------------------------------------

6.1   If:

      (a)    any provision for Taxation in the Accounts or the Net
             Working Capital Statement has proved to be an over-
             provision (as certified, if Seller so requests by the
             auditors for the time being of the Subject Company at
             the expense of Seller), except to the extent that such
             over-provision results from:

             (i)     the utilisation of a Relief which has been
                     treated as an asset of the Subject Company in
                     preparing the Accounts or the Net Working
                     Capital Statement; or 

             (ii)    a Relief which arises as a consequence of, or by
                     reference to an Event occurring (or deemed to
                     occur) after Completion; or

             (iii)   from a change in rates of Taxation appropriate
                     to the particular over-provision made after the
                     date of this Agreement; or
<PAGE>
<PAGE> 123

      (b)    any Taxation Liability to which clause 2 applies gives
             rise to a Relief which would not otherwise have arisen
             or which arises in an accounting period other than the
             one in which the Taxation Liability arises or which
             gives rise to a reduction in the amount of, or the
             elimination of, a Taxation Liability of the Subject
             Company whenever arising,

      an amount equal to such over-provision or (as the case may
      be) the amount of the Taxation Liability which is eliminated
      or the amount by which it is reduced (except to the extent
      to which it has been taken into account or credit has been
      given for it in relation to any claim in relation to any
      breach of Warranty (as determined and certified by the
      auditors for the time being of the Subject Company at the
      expense of Seller)) shall be dealt with in accordance with
      clause 6.2 below.

6.2   Where pursuant to clause 6.1 any amount (the "Relevant
      Amount") is to be dealt with in accordance with this sub-
      clause:

      (a)    the Relevant Amount shall first be set off against any
             payment then due from Seller under this Deed;

      (b)    to the extent that there is an excess, a refund shall
             be made to Seller of any previous payment or payments
             made by it under this Deed and not previously refunded
             under this sub-clause up to the amount of such excess;
             and

      (c)    to the extent that the excess referred to in sub-clause
             (b) is not exhausted under that sub-clause, the
             remainder of that excess shall be carried forward and
             set off against any future payments which may become
             due from Seller under this Deed.

6.3   For the purposes of clause 6.1(b), a Taxation Liability
      shall not be treated as being eliminated or reduced until
      the date upon which such liability is actually eliminated or
      reduced and, in particular (but without prejudice to the
      generality of the foregoing), where the Relief is the right
      to set a liability of the Subject Company to advance
      corporation tax against a liability of the Subject Company
      to corporation tax pursuant to Section 239(1) or (4) ICTA
      1988 or gives rise to a repayment of corporation tax
      pursuant to Section 239(3) ICTA 1988, the Relief shall not
      be treated as having arisen until the offset has occurred or
      the repayment has been received.

7     Payment
      -------

7.1   Where any amount is required to be paid by Seller under this
      Deed pursuant to clause 2.1(a) hereof, Seller shall pay such
      amount free and clear of all withholding for or on account
      of Taxation, save only where such withholding is required by
      law in cleared, immediately available funds on or before the
      date two business days before the date on which the Taxation
      in question is due for payment to the relevant Taxation
      Authority or, if later, five business days following the
      date on which Purchaser notifies Seller of its liability to
      make such payment.

7.2   If Seller becomes liable to make a payment under clause 2(a)
      or (b) above in respect of any amount not being a Taxation
      Liability, Purchaser will notify Seller in writing of the
      amount which Seller is required to pay and Seller shall pay
      such amount in cleared, immediately available funds on or
      before the date 14 business days after the date on which it
      receives such notice.  Any dispute as to the amount
      contained in such notice shall be determined (at the cost of
      Seller) by the auditors to the Subject Company, acting as
      experts and not arbitrators.

7.3   Sums not paid by Seller on the dates specified in clause 7.1
      and 7.2 above shall bear interest (which shall accrue from
      day to day after, as well as before, judgment at the Agreed
      Rate from the date following the said specified date up to
      and including the day of actual payment of such sums (or the
      next business day if such day of actual payment is not a
      business day) compounded quarterly.

7.4   If at any time any applicable law, regulation or regulatory
      requirement, requires Seller to make any deduction or
      withholding from any payment made in respect of any amount
      due from Seller hereunder, the amount so due shall be
      increased to the extent necessary to ensure that, after the
      making of such deduction or withholding, Purchaser receives,
      on the due date for such payment, a net sum equal to the sum
      which it would have received had no such deduction or
      withholding been required to be made, provided this clause
      7.4 shall only apply if:

      (a)    Purchaser is a resident of the United Kingdom (as that
             term is defined in Article 4 of the Double Tax
             Convention between the United Kingdom and the United
             States of 31st December 1975); and 
<PAGE>
<PAGE> 125

      (b)    has had made and had accepted any relevant applications
             for relief under such Convention.

7.5   If Seller is required by law to make any deduction or
      withholding as referred to in clause 7.4 above, Seller
      shall:

      (a)    make such deduction or withholding;

      (b)    pay the full amount deducted or withheld to the
             relevant authority in accordance with applicable law;
             and

      (c)    forthwith furnish to Purchaser the original, or a
             certified copy, of a receipt evidencing payment
             thereof.

7.6   If, following any such deduction or withholding from any
      payment by Seller as is referred to in clause 7.4, Purchaser
      shall receive or be granted a credit against or remission
      for any Taxation payable by it, Purchaser shall, subject to
      Seller having made any increased payment in accordance with
      clause 7.4 and to the extent that Purchaser can do so
      without prejudicing the retention of the amount of such
      credit and without prejudice to the right of Purchaser to
      obtain any other Relief which may be available to it,
      reimburse Seller with such amount as Purchaser shall (acting
      in good faith) certify to be such portion of such credit as
      will leave Purchaser (after such reimbursement) in no worse
      a position than it would have been had there been no such
      deduction or withholding from the payment by Seller as
      aforesaid.  Such reimbursement shall be made forthwith upon
      Purchaser certifying that the amount of such credit has been
      received by it.

8     Purchaser's Covenant
      --------------------

8.1   Purchaser hereby covenants with Seller to pay to Seller, an
      amount equivalent to:

      (a)    any Taxation for which Seller, or any other person
             falling within section 767A(2) ICTA 1988 by virtue of a
             relationship which he has with Seller, becomes liable
             by virtue of the operation of section 767A and 767B
             ICTA in circumstances where the taxpayer company (as
             referred to in section 767A(1) ICTA 1988) is the
             Company or a Subsidiary; 
<PAGE>
<PAGE> 126

      (b)    any other Taxation for which Seller becomes liable as a
             result of the failure by the Company or a Subsidiary to
             discharge it;  and

      (c)    22.5 per cent. of:

             (i)     in relation to SONSL, 30 per cent. of any
                     increase as is finally determined to be made in
                     SONSL's qualifying expenditure (as at 1st July
                     1996) for the purposes of section 25 CAA 1990,
                     in respect of its acquisition on 4th June, 1993
                     or the P344 interest in the Balmoral Field,
                     where such increase results solely from an
                     adjustment being finally determined by a
                     Taxation Authority to the consideration
                     apportioned in the agreement for its
                     acquisition;

             (ii)    in relation to the Company, 49 per cent. of any
                     increase as is finally determined is required to
                     be made the Company's qualifying expenditure (as
                     at 1st July 1996 immediately after the Economic
                     Date) for the purposes of section 25 CAA 1990 in
                     respect of its acquisition on 22nd March, 1994
                     or the P199 interest in the Ninian Field, where
                     such increase results solely from an adjustment
                     being finally determined by any Taxation
                     Authority to the consideration apportioned in
                     the agreement for its acquisition;

8.2   The covenant contained in clause 8.1 above shall:

      (a)    extend to any reasonable costs incurred by Seller or
             such other person in connection with such Taxation or a
             claim under this clause 8;

      (b)    not apply to any Taxation to the extent that Purchaser
             could claim payment in respect of it under clause 2.1
             of this Deed; and

      (c)    not apply to Taxation which has been recovered under
             section 767B(2) ICTA 1988 (and Seller shall ensure that
             no such recovery is sought to the extent that payment
             is made hereunder).
<PAGE>
<PAGE> 127

8.3   Clauses 2.2 (treatment of the payment as an adjustment to
      the purchase price), 5 (Conduct of Claims), 7 (Payments)
      shall apply to the covenant contained in this clause 8 as it
      applies to the covenant contained in clause 2.1, replacing
      references to Seller with references to Purchaser (and vice
      versa) and making any other necessary modifications.

<PAGE> 133

             (i)   imposed on Seller or any other member of any
                   consolidated, combined or unitary group that
                   includes or which at any time included the Group
                   or Seller (hereinafter "Seller's Group") (other
                   than the Group) for any taxable year; and

             (ii)  imposed on the Group in respect of its income,
                   business, property or operations or for which the
                   Group may otherwise be liable, for any taxable
                   year that ends on or before the Economic Date and,
                   with respect to any taxable year beginning before
                   and ending after the Economic Date, the portion of
                   such taxable year ending on (and including) the
                   Economic Date (hereinafter, the "Short Period")
                   (the Short Period and any taxable year that ends
                   on or before the Economic Date being collectively
                   hereinafter, the "Seller's Period") including, but
                   not limited to any Taxes imposed on the Group,
                   Seller, or Seller's Group as a result of Seller
                   and Purchaser making the Elections (as defined in
                   clause 6.8 of the Agreement); provided, however,
                   Seller will not be responsible for Taxes resulting
                   from any express or deemed election under Section
                   338 of the Code (or comparable provisions of state
                   law) where Purchaser has failed to make a valid
                   election under Section 338(h)(10) of the Code (or
                   comparable provisions of state law) as provided
                   for in clause 6.8.

      (b)    Purchaser and the Group shall indemnify and save Seller
             and members of the Seller's Group harmless from, and
             shall be entitled to any refund of, any and all Taxes
             imposed on the Group (or any successor thereto) in
             respect of its income, business, property or operations
             for any taxable year that begins after the Economic
             Date and, with respect to any taxable year beginning
             before and ending after the Economic Date, the portion
             of such taxable year commencing on the day following
             the Economic Date (hereinafter, the "Purchaser's
             Period").

      (c)    The amount of any indemnity payment required to be made
             by an indemnifying party pursuant to this paragraph 2
             shall be determined after giving effect to the present
             value (based on a discount rate equal to the short-term
             applicable federal rate as determined under Section
             1274(d) of the Code at that time) of any tax benefit
             realised or realisable by the indemnified party in
<PAGE>
<PAGE> 134

             connection with or as a result of the incurrence of the
             tax liability for which the indemnity payment is to be
             made.  In the event of a refund or credit with respect
             to a Tax for which an indemnity payment has been made
             pursuant to this paragraph 2, the indemnified party
             shall promptly pay, not later than five business days
             after receipt, to the indemnifying party the amount of
             such refund (plus any interest received with respect to
             such refund) or shall promptly pay to the indemnifying
             party the amount of such credit (plus any interest the
             crediting party would have received have it claimed a
             refund in lieu of a credit) at the time such credit
             reduces the tax liability of the indemnified party.  To
             the extent any such refund or credit (and related
             interest) is properly includible in the taxable income
             of the recipient, the amount forwarded or reimbursed to
             Seller or Purchaser shall be reduced by the tax
             liability incurred with respect to such receipt.  Any
             refunds or reimbursements not made within the time
             periods specified above shall bear interest at the
             underpayment rate or under Section 6621(a)(2) of the
             Code in effect for the period of the non-payment.

      (d)    For the purposes of this Agreement, the portion of each
             such tax that is attributable to the operations of the
             Group for such Short Period shall be (i) in the case of
             a Tax that is not based on gross or net income, the
             total amount of such Tax for the taxable year in
             question multiplied by a fraction, the numerator of
             which is the number of days in the Short Period, and
             denominator of which is the total number of days in
             such taxable year, and (ii) in the case of a Tax that
             is based on gross or net income, the Tax that would be
             due with respect to the Short Period if such Short
             Period were a short taxable year, based upon the
             Audited Accounts for the Short Period.

      (e)    (i)   The party to be indemnified shall give the
                   indemnifying party notice when any payment in
                   connection with the Tax indemnification is due. 
                   The indemnifying party shall pay to the party to
                   be indemnified, within five days of receiving
                   notice, but in no event more than two days prior
                   to the date any tax payment is due by the party to
                   be indemnified to a Taxation Authority (or, if no
                   payment is due by the party to be indemnified to a
                   Taxation Authority, on the date the Taxation
                   Authority accepts a tax overassessment or consents
                   to an assessment) an amount equal to the Tax due
                   from the indemnifying party.
<PAGE>
<PAGE> 135

             (ii)  The indemnifying party shall pay an amount equal
                   to the Tax benefit due to the party to be
                   indemnified within five days of the occurrence of
                   the earliest of:

                   (A)   the receipt of a tax benefit from a Taxation
                         Authority;

                   (B)   if the benefit is applied to other
                         liabilities due by the indemnifying party,
                         the dates the Taxation Authority accepts such
                         benefit or overassessment; and

                   (C)   if there is a Tax payment due from the
                         indemnifying party to the Taxation Authority,
                         but a benefit is allowable to the party to be
                         indemnified under the Agreement, the date the
                         Tax payment is due by the indemnifying party
                         to the Taxation Authority.

3     Returns:
      (a)    Seller shall prepare and file all federal and state Tax
             Returns required of the Group with respect to any
             taxable year (including any short taxable year) ending
             on or before the Economic Date that have not been filed
             prior to the Completion Date.  Purchaser and the Group
             shall prepare and file all Tax Returns of the Group
             with respect to any taxable year ending after the
             Completion Date.  Within sixty days after Completion
             Date, Purchaser shall provide Seller with sufficient
             federal tax accounting data and information to support
             a determination of the federal income tax liability of
             the Group for the Seller's Period, as well as
             sufficient data and information to allow Seller to
             prepare the state Tax Returns.  For purposes of
             allocating the items of income, gain, deductions and
             loss of the Company to the period ending on the
             Completion Date for purposes of Treasury Regulations
             Section 1.1502-76(b), such allocation shall be based
             upon an interim closing of the books of the Company.

      (b)    After the Completion Date, Seller will be entitled to
             file amended Tax Returns for the Group for the Seller's
             Period, to control the audit of any such original or
             amended returns for the Seller's Period, including but
             not limited to extending the applicable statute of
             limitations, and settling of litigated claims, and
             Purchaser will co-operate and cause the Group to
             execute such powers of attorney and other documents as
             are necessary to carry out this intent.
<PAGE>
<PAGE> 136

      (c)    Seller shall prepare and timely file, or cause to be
             prepared and timely filed, all Tax Returns described in
             paragraphs 3(a) and (b) above and shall pay any Taxes
             shown thereon to be due.  Such Tax Returns that
             included the periods up to completion shall be prepared
             on a basis consistent with the basis upon which
             comparable Tax Returns were prepared for prior periods.

4     Co-operation

      (a)    Purchaser and Seller shall furnish or cause to be
             furnished to each other, upon request, as promptly as
             practicable, such information (including access to
             books and other records) and assistance as is
             reasonably necessary for the filing of any Tax Return,
             for the preparation for or conduct of any audit, and
             for the prosecution or defence of any claim, suit or
             proceeding relating to any proposed tax adjustment. 
             Purchaser and Seller shall co-operate with each other
             in the conduct of any audit or other similar
             proceedings and each shall execute and deliver such
             powers of attorney and other documents as are necessary
             to carry out this intent.

      (b)    If, in the course of the any member of the Group being
             audited by any Taxation Authority, either Seller or
             Purchaser requests from the other information, records
             or documentation normally maintained to support the
             determination of Tax liabilities, and required to be
             maintained under the record retention provisions
             required by law, regulations, procedure or revenue
             ruling, and such item of documentation was not
             maintained in accordance with the record retention
             provisions described herein and, therefore, cannot be
             produced or is unavailable, and the lack of such
             documentation, information or record results in an
             adverse audit finding against the requesting party on
             the Tax issue to which such document relates by the
             Taxation Authority conducting the audit, then the party
             failing to supply the requested item of information
             shall indemnify the requesting party for additional
             Taxes, interest and penalty relating to the
             undocumented tax issue on the same basis as provided in
             paragraph 2 above.

5     Contests

      Purchaser and Seller shall each promptly give written notice
      to the other of any examination, audit, inquiry or proposed
      or actual assessment by a federal, state or local covering
      any potential liability for Taxes where a right may exist of
      one party to demand payment for such Tax from, or be
      indemnified by, the other party.  Whenever any Taxation
      Authority informs Purchaser or the Group of a claim,
      assessment or other dispute concerning an amount of Taxes
      for which Seller is or may be liable under this Agreement,
      Purchaser shall promptly inform Seller in writing, and
      Seller shall have the right to control any resulting
      proceedings and to determine whether and when to settle any
      such claim, assessment or dispute to the extent such
      proceedings or determinations affect the amount of Taxes for
      which Seller is liable under this Schedule; provided,
      however, that Purchaser and the Group are not hereby
      relieved of their responsibilities to handle an audit unless
      expressly assumed by Seller.  Whenever any Taxation
      Authority informs Seller of a claim, assessment, or other
      dispute concerning an amount of Taxes for which Purchaser is
      or may be liable under this Agreement, Seller shall promptly
      inform Purchaser in writing, and Purchaser shall have the
      right to control any resulting proceedings and to determine
      whether and when to settle any such claim, assessment or
      dispute to the extent such proceedings or determinations
      affect the amount of Taxes for which Purchaser is liable
      under this Agreement.  Each party hereto agrees to give the
      other party the right of reasonable consultation regarding
      the matters subject to this paragraph which could affect the
      other.  The omission to notify the indemnifying party shall
      not believe it from liability which it may have to the
      indemnified party to the extent the indemnifying party is
      not prejudiced by such omission.

6     Termination of Tax Allocation Agreement

      Effective as of the Economic Date, all liabilities and
      obligations between Seller and the Group under any tax
      allocation agreement or other similar arrangement in effect
      prior to the Economic Date shall be extinguished in full,
      and any liabilities or rights existing under any such
      agreement or arrangement shall terminate and shall no longer
      be enforceable.

7     Time Limitation

      The agreements in this Schedule shall remain in effect for a
      period of one year past any statute of limitations governing
      the duration of either party's rights or liabilities in any
      particular instance.  Seller shall notify Purchaser at least
      60 days prior to the expiry of the statute of limitations
      and notify Purchaser within 30 days of any extension of the
      statute of limitations.

(a)  The consolidated financial statements of Sun Company, Inc. and
     subsidiaries for the above period contain the accounts of all
     subsidiaries that are controlled (generally more than 50 percent owned)
     except those engaged in real estate and international production
     operations.  Real estate operations are accounted for as an investment
     held for sale and included in the computation of the ratio of earnings
     to fixed charges, while international production operations are being
     treated as a discontinued operation and excluded from the computation. 
     (See Notes 2 and 3 to the condensed consolidated financial statements.) 
     Affiliated companies over which the Company has the ability to exercise
     significant influence but that are not controlled (generally 20 to 50
     percent owned) are accounted for by the equity method.
(b)  Represents one-third of total operating lease rental expense which is
     that portion deemed to be interest.
(c)  Earnings are inadequate to cover fixed charges by $79 million.
